Abstract
Disclosed is a fluorine-substituted Pi(π)-bridge selenide polymer acceptor material, its preparation and application. The selenide polymer acceptor material is named PYSe2FT and is synthesized by Knoevenagel condensation reaction and Still cross-coupling reaction; the material PYSe2FT takes a selenium-substituted core donor unit as a main structure, and combines a difluoro-substituted thiophene π-electronic connection unit, where the selenium-substituted core donor unit and the difluoro-substituted thiophene π-electronic connection unit can effectively regulate and control the molecular energy level, so that molecules generate good accumulation, thus making PYSe-2FT an excellent polymer acceptor material.
