Abstract

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.

Description

technical field

[0001] The invention belongs to the technical field of organic materials, and in particular relates to a porphyrin copolymer containing thienothiadiazole units, its preparation method and application. Background technique

[0002] Today's world economy is mainly based on fossil energy, such as coal, oil and natural gas. However, these non-renewable fossil energy sources are constantly being exhausted. Since the beginning of the 21st century, global energy issues and the ensuing environmental pollution and climate warming have become increasingly prominent and gradually intensified. Solar energy is considered to be one of the most promising renewable energy sources because of its widespread and vast distribution, large amount of resources, no pollution, cleanliness, safety, and easy access.

[0003] In order to make full use of the energy irradiated by sunlight, people continue to develop new materials that can absorb sunlight. Among them, inorganic semicond...
