Embodiment 1

[0032] (1) Heat a 250ml single-necked round-bottom flask with a heating gun and pump air at the same time. After heating and pumping for 20 minutes, stop heating and pumping. After the flask is cooled, add benzo[1,2-B: 3 , 4-B': 5,6-B'] trithiophene (1.23g, 5mmol), then pump and inflate the flask (nitrogen) 10 times, add 100ml of tetrahydrofuran into the flask, and put the flask into a liquid nitrogen tank Slowly add butyl lithium solution (25mmol, 10.42 ml) dropwise to the flask after the reaction temperature is lowered to -78°C. The dropping process should be completed within 45 minutes. After rising to room temperature, react for 1 hour, add tributyltin chloride (25mmol, 6.78ml) after dropping the temperature to -78°C, remove the liquid nitrogen tank after the dropwise addition, and react for 24 hours after the temperature of the system rises to room temperature, the whole The experimental process was carried out under the protection of nitrogen, and a brown-black solution ...

Abstract

The invention relates to the technical field of organic semiconductor materials. In order to solve the problems of low solubility and low electrical properties of organic semiconductor materials, the invention proposes a star-shaped silicon-containing polymer with trithienoacene as the core and a preparation method thereof In terms of application and application, the trithienophenyl group introduced in the present invention has a larger coplanar π-conjugated structure, which is beneficial to expanding the range of charge delocalization, thereby facilitating obtaining higher electrical properties. In addition, the introduction of the star configuration is also beneficial to improve the solubility of the compound, thus obtaining a polymer with higher solubility. The trithienophenyl star-shaped silicon-containing polymer has a structural formula as shown in formula (I): (I).

Description

technical field [0001] The invention relates to the technical field of organic semiconductor materials, in particular to a star-shaped silicon-containing polymer and a preparation method thereof. Background technique [0002] In recent years, the development of organic semiconductor materials has been extremely rapid. Organic semiconductor materials play an important role in organic optoelectronic devices such as field effect transistors (OFETs), organic light emitting diodes (OLED), organic solar photovoltaic cells (OPV) and other organic optoelectronic devices. potential application value.
