Abstract:
1. A fluorescent molecular wire comprising a polymer main chain having a linked conjugated system, wherein an optically active substituent is linked to the polymer main chain and is conjugated with the polymer main chain, the optically active substituent being represented by the following formula (I): where R 1 represents a hydrogen atom or an alkyl group having 1 to 10 carbon atoms R 2 , R 3 , R 4 , R 5 , R 6 , R 7 , R 8 , and R 9 represent independently a hydrogen atom, a linear alkyl group having 1 to 30 carbon atoms that may have a substituent, a branched alkyl group having 2 to 30 carbon atoms that may have a substituent, a cyclic alkyl group having 3 to 30 carbon atoms that may have a substituent, an aryl group having 6 to 30 carbon atoms that may have a substituent, or an aralkyl group having 7 to 30 carbon atoms that may have a substituent, and R 3 and R 7 may be bonded respectively to R 4 and R 8 to form an alkylene group having 2 to 60 carbon atoms that may have a substituent; and R 10 and R 11 represent independently a hydrogen atom or an alkyl group having 1 to 15 carbon atoms that may have a heteroatom, and R 10 and R 11 may be bonded to form an alkylene group having 2 to 30 carbon atoms that may have a heteroatom, and wherein when a complex between the optically active substituent and a primary amine is formed, a charge transfer from a receptor site to the polymer main chain is caused, thereby resulting in a quenching of the fluorescence in the fluorescent molecular wire, and wherein the polymer main chain having a linked conjugated system is a polyphenylene structure, a polythiophene structure, a poly(phenylene thiophenylene) structure, a poly(phenylene ethynylene) structure, a poly(thiophenylene ethynylene) structure, or a poly(phenylene vinylene) structure, a polyarylene structure, a poly(arylene ethynylene) structure, or a poly(arylene vinylene) structure.
