Syntheses and properties of copoly(2,5 -dialkoxy-p-phenylenebutadiynylene/arylenebutadiynylene)s

摘要

Copoly(2,5-didodecyloxy-p-phenylenebutadiynylene/arylenebutadiynylene)s were synthesized by polycondensition of 2,5-didodecyloxy- 1,4-dicthynylbenzene with m-diethynylbenzene derivatives and 2,5-diethynylthiophene, respectively, in presence of a Cu-amine catalyst under O_2. Solubility and processability of the polymers were greatly improved by the copolymerization. Most of the copolymers have enhanced fluorescence intensity than corresponding homopolymers.
