| Abstract |
Phenyl substituents attached to the polyene chain provide not only improved stability, but also diverse physicochemical characteristics, depending on the electronic nature of the substituent. Carotene with tetra-Phenyl substituents has better electrical conductivity than carotene with di-Phenyl substituents. Carotenoid molecular wires containing tetra-Phenyl substituents can be assembled by the Wittig reaction between tetra-Phenyl-substituted-dial and 4-thiomethylbenzyl phosphonium bromide(Wittig salt). tetra-Phenyl-substitued-dial can be effectively synthesized by the Julia-Kocienski olefination of the Phenyl-substituted-C5-BT(benzothiazole)-sulfone with C10 2,7-diphenyl-2,4,6-octatrienedial. |
