Problems solved by technology

However, the processing of most high-performance semiconducting conjugated polymers will use toxic solvents such as chloroform and chlorobenzene, and the use of these solvents will not only affect human health, but also pollute the environment
However, there are very few high-performance semiconducting conjugated polymers that can be processed by non-chlorinated solvents reported in the literature, mainly for DPP (diketopyrrolopyrrole) backbone engineering, such as asymmetric structures (Adv.Mater.2016 ,28,943–950) and random copolymerization (Adv.Funct.Mater.2015,25,4844–4850), which greatly limit the research and application of solution-processable high-performance semiconducting conjugated polymers

Abstract

The invention discloses a highly-soluble high-performance semiconductor conjugated polymer and a synthetic method thereof. By introducing length-adjustable long straight hybrid siloxy group chain as aside chain, a series of highly-soluble high-performance bioxindol conjugated polymers are obtained. The synthesized novel high-performance semiconductor conjugated polymer can be used as a hole charge transfer material and applied to organic field-effect transistors. The semiconductor conjugated polymer of the invention has great solubility, and can be dissolved in solvents such as chloroform, toluene, hexane and ethyl acetate, etc. The invention is of great guiding significance for designing and synthesizing the high-performance semiconductor conjugated polymer for non-chlorine solvent processing.

Description

technical field [0001] The invention belongs to the field of conjugated polymers, and in particular relates to a highly soluble and high-performance semiconductor conjugated polymer and a synthesis method thereof. Background technique [0002] Due to the advantages of light weight, low cost and good flexibility, conjugated polymers are expected to be widely used in organic field effect transistors. The most studied of the conjugated polymers is the donor-acceptor (D-A) conjugated polymer, which is due to the push-pull interaction between the donor and the acceptor of the D-A conjugated polymer that enhances the intramolecular and intermolecular interactions. force, greatly improving the charge transport performance. However, the processing of most high-performance semiconducting conjugated polymers will use toxic solvents such as chloroform and chlorobenzene, and the use of these solvents will not only affect human health, but also pollute the environment. However, there a...
