Abstract
A porphyrin copolymer containing thienothiadiazole units, preparation method and uses thereof are disclosed. The copolymer has the structural formula (I), wherein: R1, R2, R3, R4 are same or different and each represents a C1-C32 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.
