This invention relates to the production of chemiluminescent light, particularly to the production of blue/violet light within the range of about 390 nm to less than 438 nm, and most particularly to the use of compounds composed of symmetrically and asymmetrically substituted anthracenes which are effective for increasing the production of such blue/violet light when used as fluorescers in conjunction with chemiluminescent systems.
The principle techniques for the production of chemiluminescent light comprising the reaction of an oxalate solution including a dye with a solution of hydrogen peroxide containing a suitable catalyst have been well described in the following U.S. Pat. Nos. 6,740,263; 5,232,635; 4,717,511; 4,678,608; 3,888,786; 3,775,336; 3,749,679; 3,597,362; 3,557,233; 3,391,068; 3,391,069, which are incorporated herein by reference.
Chemiluminescence is produced by a reaction, in the liquid phase, of an activator such as hydrogen peroxide with a fluorescent agent and an oxalate. Optionally, other secondary compounds can be present such as catalysts, dyes etc. The production of chemiluminescent light by the reaction of a catalyzed hydrogen peroxide solution with a fluorescer solution is well known in the art. Blue, green and yellow chemiluminescent light has been produced depending upon the particular fluorescer employed in the fluorescer solution. Examples of these prior art chemiluminescent light-systems can be found in one or more of the following U.S. Pat. Nos. 3,749,679; 3,391,068; 3,974,368; 3,557,233; 3,597,362; 3,775,336; 3,888,786.
Historically, the light output of blue chemiluminescent devices has been based upon 9,10-diphenylanthracene (DPHA) and 2-chloro-9,10-bis(4-methoxyphenyl)anthracene (BPEN). However, although the light output is measured from 400-500 nm, most of the substituted 9,10-diphenylanthracene derivatives have chemiluminescent emission maxima greater than 445 nm. The most common blue used in chemiluminescent devices is BPEN with an emission maximum of 451 nm. None of the reported non-polymeric substituted diphenylanthracene dyes used for chemiluminescence has a listed emission maximum below DPHA (438 nm). This invention teaches the development of dyes suitable for oxalate/peroxide chemiluminescent systems with a spectrum having an emission maximum at a wavelength below the one observed for DPHA, but at wavelengths greater than the ultra-violet region. This would enable the production of a chemiluminescent system with greater output in the violet region of the visible spectrum, particularly, a chemiluminescent system which produces light having an emission maximum from about 390 nm to less than 438 nm without the need for filters to protect the observer from ultraviolet radiation.
U.S. Pat. No. 3,888,786 to Maulding relates to a chemiluminescent system to obtain chemiluminescent light by reacting an oxalic-type compound of the group consisting of an oxalic-type ester with a hydroperoxide compound in the presence of a solvent and chloro, fluoro, or lower alkyl bis(phenylethynyl)-substituted aromatic compound as a fluorescer. Similarly, U.S. Pat. Nos. 3,729,426, 3,948,797, 4,017,415 and 5,122,306 teach the use of substituted anthracene derivatives such as 9,10-bis(phenylethynyl)anthracene, 9,10-bis(4-methoxyphenyl)-2-chloroanthracene, monochloro-substituted 9,10-bis(phenylethynyl)anthracenes such as 1-chloro-9,10-bis(phenylethynyl)anthracene, dichloro-substituted 9,10-bis(phenylethynyl)anthracenes such as 1,8-dichloro-9,10-bis(phenylethynyl)anthracene, 1,5-dichloro-9,10-bis(phenylethynyl)anthracene, 2,3-dichloro-9,10-bis(phenylethynyl)anthracene, 9,10-diphenylanthracene and the like, as suitable fluorescers for chemiluminescent systems. U.S. Pat. No. 3,970,660 to Bollyky is directed toward a chemiluminescent system comprising (1) derivatives of a polycarbonyl compound substituted with at least one nitrogen-containing hetero group and which may have an alkanol or amine substituent, (2) a hydroperoxide compound, (3) a diluent, and (4) a fluorescer, inclusive of halogen substituted anthracenes, said ingredients in combination producing visible chemiluminescent light and a process of producing such light. U.S. Pat. No. 4,076,645 to Vega teaches compositions and methods for producing chemiluminescence by the reaction of bis(6-carbopentoxy-2,4,5-trichlorophenyl)oxalate with a peroxide in presence of 9,10-bis(phenylethynyl)anthracene the initial luminosity on mixing these reaction components in a suitable diluent is increased by using the specific concentration of bis-oxalate ester component in the range from 0.05 to 0.09 mole per liter in the reaction mixture.
U.S. Pat. No. 4,859,369 to Baretz et al, teaches aqueous chemiluminescent systems, inclusive of halogen substituted anthracene fluorescers including those emitting in the blue region of the spectrum chemiluminescent systems, which have been found to exhibit improved chemiluminescence due to the presence of minor amounts of a water-soluble polymer.
U.S. Pat. No. 5,232,635 to Van Moer et al is directed toward new derivatives of anthracene for the emission of a blue chemiluminescent light. The derivatives are of 9,10-bisphenylanthracene substituted at the 2 position of the anthracene ring and on the phenyl groups including 9,10-bis(4-fluorophenyl)-2-fluoroanthracene. The production of turquoise chemiluminescent light is also disclosed by mixing said derivatives with a green 9,10-bis(phenylethynyl) anthracene.
U.S. Pat. No. 6,740,263 to Park et al describes an anthracene and chemiluminescent compositions as shown below. Wherein, R is an alkyl group having 1-8 carbon atoms, and X1 and X2 are independently hydrogen or a halogen.
The disclosure of Park et al relates to an anthracene compound and a chemiluminescent composition comprising the compound, and more particularly to a novel anthracene compound, which is capable of emitting a blue light of a high intensity for a prolonged period of time compared with conventional anthracene compounds used as luminescent dyes in chemiluminescent compositions emitting blue light, and a chemiluminescent composition comprising the anthracene compound.
The above referenced prior art disclosures fail to teach or suggest the novel compounds as instantly disclosed, nor do they teach a chemiluminescent system which produces light having an emission maximum from about 390 nm to less than 438 nm.
It is a primary objective of the instant invention to teach new species of fluoro-substituted 9,10-diphenylanthracenes including symmetrically and/or asymmetrically substituted constituents.
It is a further objective of the instant invention to provide fluorescer compounds based upon symmetrical and asymmetrical 9,10-diphenylanthracene derivatives of Formula (1), where the substituents on the anthracene labeled A1, A2, A3, A4, A5, A6, A7, and A8 are either fluorine or hydrogen.
It is a further objective of the instant invention to provide a chemiluminescent composition comprised of a solution of the fluorescer and oxalate, which when mixed with a solution of hydrogen peroxide in an appropriate solvent provides a chemiluminescent system exhibiting improved light output in the spectral region of about 390 nm to less than 438 nm particularly, a chemiluminescent system which produces light having an emission maximum from about 390 nm to less than 438 nm, and more specifically a chemiluminescent system which produces light having an emission maximum in the region from about 400 nm to about 420 nm.
In accordance with the present invention, the oxalate compound is a bis(phenyl) oxalate ester having the formula:
In a preferred embodiment the oxalate is bis(2,4,5-trichloro-6-carbopentoxyphenyl)oxalate.

The present invention can be achieved by providing a compound represented by Formula (1):
The new species of anthracenes according to the invention may be prepared by a method, according to one of the Reaction Schemes given below.
One process of the present invention, as shown in Reaction Scheme 1, to obtain derivatives in Formula (1) where Ar1 and Ar2 are the same may be described as a synthetic process comprising steps of:
Fluorinated anthraquinones represented by Formula (4) may be purchased from commercial sources or made as described by Tannaci et al. (J. Org. Chem. 2007, 72, 5567-5573), Mallory et al. (J. Am. Chem. Soc. 1990, 112, 2577-2581), and Moer et al. (U.S. Pat. No. 5,232,635).
Alternatively, symmetrical derivatives may be made via the Suzuki-Miyaura reaction or variation thereof using either a 9,10-dichloroanthracene, 9,10-dibromoanthracene, or 9,10-diiodoanthracene derivative and an aryl boronic acid, boronic ester, or trifluoroborate. Additionally, a 9,10-anthracenediboronic acid, equivalent ester, or trifluoroborate can be reacted with an aryl halide or triflate. Both pathways are as shown in Reaction Scheme 2 comprising the reaction of:
Another process of the invention, as shown is Reaction Scheme 3, to produce asymmetrical anthracene derivatives, where Ar1 and Ar2 are not the same, may be described as a synthetic process comprising steps of:
Alternatively, the asymmetric derivatives of the present invention can be made by via a synthetic coupling reaction as shown in Reaction Scheme 4 containing:
The production of a chemiluminescent system exhibiting a blue/violet emission spectrum with a maximum in the range of about 390 nm to less than-438 nm according to the present invention is accomplished by the combination of two solutions, A and B:
Compounds which are generally suitable to catalyze the reaction between the activator and oxalate type esters are basic compounds, such as amines, hydroxides, alkoxides, carboxylic acid salts and phenolic salts. Preferred salts of carboxylic acids and phenols are derived from compounds having a pKa in the range of from about 1 to about 6 as measured in aqueous solution, for example tetrabutylammonium salicylate, sodium salicylate, ethyl-2-acetoxy salicylate, various tetraalkylammonium salicylates, lithium salicylate, lithium 5-t-butyl salicylate sodium-5-bromosalicylate, sodium-5-chlorosalicylate, and sodium-5-fluorosalicylate or the like, with the preferred catalyst being sodium salicylate.
Starting materials and solvents were purchased from Aldrich, Matrix, Synthonix, and Alfa Aesar. All of the desired compounds were analyzed via HPLC, and their spectra (absorption, chemiluminescent emission, and NMR) recorded.
To a suspension of 6.25 g of 9,10-anthraquinone in 60 mL of anhydrous 1,4-dioxane, was added 0.1 mole of pentafluorophenylmagnesium bromide in 30 mL of diethyl ether prepared as described in Organic Synthesis, Coll. Vol. 6, p. 875. The mixture was brought to a reflux and held there overnight. The reaction was quenched in a mixture of 25 mL of saturated aqueous ammonium chloride and 25 mL of water. After bringing the pH of the aqueous portion of the solution to pH 3-4 using dilute aqueous hydrochloric acid, 100 mL of ethyl acetate was added. The layers were separated, and the aqueous layer was extracted with an additional 100 mL of ethyl acetate. The combined organic extracts were dried with magnesium sulfate and concentrated. The residue was recrystallized from toluene to give 8.66 g of off-white crystals.
The reduction of the diol was accomplished by taking 5.44 g of 9,10-bis(pentafluorophenyl)-9,10-dihydro-9,10-anthracenediol in 50 mL of acetic acid and refluxing it with 9 g of potassium iodide and 9 g of sodium hypophosphite for 4 hours. After cooling, white crystals were filtered off. The crude product was recrystallized using a 1:1 mixture of toluene and hexane to yield 2.00 g of 9,10-bis(pentafluorophenyl)anthracene with a melting point of 337-338° C.
Symmetrically and asymmetrically substituted anthracenes can be made via Reaction Scheme 2 and Reaction Scheme 3 or a variation thereof using the procedures in the following: patents and patent applications, US 2004/0161633 A1, U.S. Pat. No. 6,815,094 B2, US, 2007/0176544 A1; literature references, Org. Lett. 2007, 9, 4893-4896. J. Am. Chem. Soc. 2008, 130, 1012-1016, and J. Org. Chem. 2008, 73, 5589-5591; and references therein.
This compound was made using the method depicted in Reaction Scheme 4. A flask with a magnetic stir bar was charged with 1.00 g of potassium carbonate, 0.15 g of dicyclohexylphosphinodimethoxybiphenyl (S-Phos), and 0.04 g of palladium acetate. The reaction vessel was evacuated and backfilled with argon three times. A solution of 1.29 g of 2,3,5,6-tetrafluoroanisole in 8 mL of isopropyl acetate was added via syringe, and the reaction mixture was stirred for one minute. A solution of 9-bromo-10-phenylanthracene in 4 mL in isopropyl acetate was added. The reaction mixture was heated to 80° C. and held at that temperature overnight. The reaction was filtered and the crude material purified via column chromatography on silica gel using 5% diethyl ether in heptane to yield 350 mg of a white solid with a melting point of 153-154° C.
This method was used to attach pentafluorophenyl, 2,3,5,6-tetrafluorophenyl, and 2,3,5,6-tetrafluoro-4-methoxyphenyl groups to a 9-haloanthracene or a 9-halo-10-arylanthracene as described in Org. Lett. 2006, 8, 5097-5100 and references therein.
The light output of the compounds was also tested. The process for producing chemiluminesence is described as follows;
