Claims
- 1. A 1,3-pentadiene derivative having formula (I):
- A--CH.dbd.CH--CH.dbd.CH--CH.sub.2 --A (I)
- wherein: A represents ##STR178## in which Ar represents (a) a phenylene group which may be substituted with a substituent selected from the group consisting of an alkyl group having 1 to 4 carbon atoms and an alkoxy group having 1 to 4 carbon atoms; (b) a biphenylene group; or (c) a naphthylene group which may be substituted with a substituent selected from the group consisting of an alkyl group having 1 to 4 carbon atoms and an alkoxy group having 1 to 4 carbon atoms; R.sup.1 and R.sup.2 each represent (i) an alkyl group having 1 to 4 carbon atoms substituted with a phenyl group which may be substituted with an alkyl group having 1 to 4 carbon atoms or an alkoxyl group having 1 to 4 carbon atoms or (ii) a phenyl group which may be substituted with a substituent selected from the group consisting of an alkyl group having 1 to 4 carbon atoms, an alkoxy group having 1 to 4 carbon atoms, a halogen atom, and a phenyl group.
- 2. The 1,3-pentadiene derivative of claim 1, wherein at least one of R.sup.1 and R.sup.2 is phenylmethyl or phenyl.
- 3. The 1,3-pentadiene derivative of claim 1, wherein Ar is naphthylene.
- 4. The 1,3-pentadiene derivative of claim 1, wherein Ar is phenylene.
