Therefore, the modified porous organic framework can be applied to catalysis, CO2 carriers and O2 carriers. The reaction equation of the protoporphyrin IX and the tetrazine group of the porous organic framework is shown in Table 2.

The storage solvent is for isolating the modified porous organic framework from the oxygen and moisture of the air so as to prolong the lifetime of the modified porous organic framework. Therefore, a substance which can achieve the aforementioned functions can be the storage solvent of the modified porous organic framework. The storage solvent can be identical to or different from the solvent of the mixing solution in Step 110 according to practical needs. The storage solvent can be, but is not limited to, N,N-diethylformamide or N,N-dimethylformamide.

In Step 230, a phase transformation step is conducted, wherein the modified porous organic framework is immersed in another solvent for a solvent replacement (i.e., for replacing the original solvent for immersing the modified porous organic framework), then the modified porous organic framework is dried so as to obtain a modified porous organic framework with a different lattice structure. The original solvent refers to the solvent of the mixing solution or the storage solvent. The solvent used in the phase transformation step is different from the solvent of the mixing solution or the storage solvent.

For example, when the porous organic framework is a metal organic framework, the precursor of the porous organic framework can be the compounds providing the first ligand and the compounds providing the metal source of the metal clusters. In other words, the porous organic framework can be assembled in advance, then the tetrazine groups and the reactive groups react with each other, so that the porous organic framework and the first material are combined. Alternatively, the compounds providing the first ligand of the precursor of the porous organic framework can react with the reactive groups via the tetrazine groups, so that the compounds providing the first ligand can be firstly combined with the first material then coordinated with other components of the precursor of the porous organic framework to assemble the porous organic framework.
With the porous organic framework including the tetrazine groups, and the reactive groups of the first material being alkenyl groups, alkynyl groups, aldehyde groups, ketone groups or a combination thereof, the porous organic framework can be combined with the first material through a click reaction so as to feature the porous organic framework with different properties, which is simple and can broaden the application scope of the porous organic framework. Furthermore, with the first material having its own functionalities and the porous organic framework having its own functionalities, the porous organic framework composite according to the present disclosure can present the functionalities of both of the first material and the porous organic framework.

5. The measuring method of nitrogen adsorption: a sample with an amount of 15 mg is activated and is grinded into finer powders then put into a sample tube. The sample tube is installed in a degas pore of an instrument (model: ASAP 2020) then is heated at 180° C. under vacuum (10−5 torr) for 12 hours, so that the water and solvent in the pores of the sample can be removed. The weight of the sample which has been removed the water and the solvent is about 60 mg. Follow by placing the sample tube at a sample port, wherein the nitrogen adsorption capacity of the sample is measured by immersing the sample tube in liquid nitrogen (77K) with a volumetric method. The measured range is as follows: 1.00×10−6≤P/P0≤1.00. The adsorption isotherms are obtained by plotting the nitrogen adsorption volume (cm3/g) on Y axis and the partial pressure (P/P0) on X axis. The adsorption isotherms can be transformed into adsorption curves by programs, then the pore distribution diagram, the information of BET area and the information of Langmuir area can be obtained with other software (such as OriginalPro 2016). The sample can be activated by immersing the sample in DMF and standing for one day, then the DMF is replaced by ether for three times, and follow by drying the sample at 70° C. for 2 hours.

The nitrophenyl easer substrate, such as p-nitrophenyl palmitate (p-NPP) can be hydrolyzed by the lipase so as to generate p-nitrophenyl (p-NP) and fatty acids (in this example, palmitic acids). The absorbance of p-NP at the wavelength 405 nm is measured. The lipase activity can be calculated by performing an analysis in a 96-well microtiter plate. The definition of the activity unit (U) of the lipase is as follows. An activity unit is the amount of enzyme used for generating 1 μmol of p-NP per minute by hydrolyzing.

Furthermore, because of the relationship between the length of the modifying group, i.e., the cetyl group, and the pore size of the porous organic framework AlTz68, the cetyl group can be modified both on the surface and in the pores of the modified porous organic framework AlTz68-C18′. Accordingly, the porosity of the modified porous organic framework AlTz68-C18′ is smaller than that of the modified porous organic framework AlTz68-C18. According to the present disclosure, whether the modifying group disposed in the pores of the porous organic framework or not can be decided by choosing the order of the modifying step and the phase transformation step or the kind of the porous organic framework and the kind of modifying groups, so that the porosity of the modified porous organic framework can be adjusted according to practical demands.

As shown in
Example 4: modified porous organic framework ZrTz68-C18. The manufacturing method is as follows. A mixture of 0.045 mmole ZrCl4, 0.045 mmole H2TZDB, 0.01 ml trifluoroacetic acid and 2.5 ml DMF is heated at 120° C. for 2 days. The solid product is washed with 2.0 ml DMF for 3 times then immersed in DMF for 2 days, and further immersed in CHCl3 for another 2 days. Afterword, the mixture of the solid product and the CHCl3 is heated at 90° C. for 12 hours so as to obtain the porous organic framework ZrTz68. The porous organic framework ZrTz68 is kept storage by immersing in DMF till conducting the following experiments.
A mixture of 10.0 mg ZrTz53, 5.0 ml CHCl3 and 2.0 ml 1-octadecene is conducted at 60° C. for 1 hour so as to synthesize the modified porous organic framework ZrTz68-C18, then the CHCl3 is removed by heating at 70° C. for 1 hour so as to obtain the modified porous organic framework ZrTz68-C18.
According to the experimental analysis, the porous organic framework ZrTz68-C18 of Example 4 includes two kinds of repeated units, which form pores of tetrahedron and pores of octahedron, respectively. The main difference between Example 4 and Examples 2-3 is the metal sources which provide the metal clusters used in manufacturing AlTz68 and ZrTz68, and the structures of the porous organic framework are different thereby. That is, the porous organic framework with different structure can be obtained by using different precursor of the porous organic framework. Therefore, the kind of the precursor of the porous organic framework can be selected to feature the porous organic framework with a proper structure (for example, a desired pore shape and pore size), so as to satisfy practical demands. Moreover, because of the relationship between the length of the modifying group, i.e., the cetyl group, and the pore size of the porous organic framework ZrTz68, the cetyl group is favorably modified on the surface of the modified porous organic framework ZrTz68-C18. Accordingly, it is favorable for maintaining the porosity of the modified porous organic framework ZrTz68-C18.
