Abstract

The invention discloses a semi-fluoroalkyl containing side chain substituted pyrrolo pyrroledione polymer, and particularly relates to the semi-fluoroalkyl containing side chain substituted pyrrolo pyrroledione polymer as well as a preparation method and an application of the semi-fluoroalkyl containing side chain substituted pyrrolo pyrroledione polymer. The provided synthesis route has the advantages of simplicity, high efficiency, low synthesis cost, good universality and repeatability, and the like, and can be popularized and applied to the synthesis of pyrrolo pyrroledione polymers of other various substituent groups. The migration rate of OTFTs (Organic Thin Film Transistors) prepared by taking the polymer PC10DPPBT as an organic semiconductor layer is as high as 0.0082 cm<2>/V.s, and the excellent application prospect of the polymer material in the OTFTs is fully shown.

Description

technical field [0001] The invention relates to a diketopyrrolopyrrole polymer substituted with a semifluoroalkyl side chain, in particular to a diketopyrrolopyrrole polymer substituted with a semifluoroalkyl dovetail side chain, a preparation method and application thereof. Background technique [0002] Since the invention of the conductive polymer polyacetylene, scientists have begun to develop organic semiconductor materials to replace the widely used inorganic semiconductor materials. Organic field-effect transistors with organic semiconductor materials as active layers have also received attention. With the unremitting efforts of scientists and the rapid development of material science and processing technology, the performance of organic field effect transistors has been greatly improved and improved, and will soon be used in people's production and life. It has strong competitive potential and broad application prospects in terms of low-cost preparation and high flex...
