PORPHYRIN COPOLYMER CONTAINING THIENOTHIADIAZOLE UNITS, PREPARATION METHOD AND USES THEREOF

摘要

A porphyrin copolymer containing thienothiadiazole units, preparation method and uses thereof are disclosed. The copolymer has the structural formula (I), wherein: R 1 , R 2 , R 3 , R 4 are same or different and each represents a C 1 -C 32 alkyl; n is an integer of 1-100. The copolymer comprises fluorene units, thienothiadiazole units and porphyrin units, which enhance the density of electron cloud in copolymer skeleton, make the band-gap of the copolymer become narrow, thereby broaden the spectral response range of the copolymer, and improve the photoelectric transformation efficiency.
