Abstract

The invention relates to the technical field of organic synthesis, in particular to a polymer containing DPP, thiophene and fluorothiophene structural units and a preparation method and application ofthe polymer. R in the three-component polymer is alkyl, the number of carbon atoms is 6-16, n is a natural number ranging from 1 to 100, and x is larger than 0 and smaller than 1. By adjusting the ratio of thiophene to fluorothiophene, the photoelectric material with excellent performance is obtained. Repetitive units in the polymer can enhance charge transfer in a compound and improve the sunlight capture capability and hole transport capability. The preparation method is simple and controllable, and has a good application prospect in the photoelectric fields of solar cell devices, organic electroluminescent devices, organic field effect transistors and the like.

Description

technical field

[0001] The invention relates to the technical field of organic synthesis, in particular to a polymer containing DPP, thiophene and fluorothiophene structural units, a preparation method and application thereof. Background technique

[0002] In recent years, organic optoelectronic functional materials with high mobility have attracted extensive attention as an important part of organic integrated devices. Organic field-effect transistors are expected to replace traditional silicon-based field-effect transistors in many application fields due to their advantages of low cost, easy modulation and simple process, and have more potential application prospects in flexible devices such as wearable devices. As the core component of organic field effect transistors, organic semiconductor materials play a key role in the properties of devices. Therefore, the design and synthesis of high-performance organic semiconductor materials and functional materials have become th...
