The following formula (I): Where n is a positive integer less than 101; R 1 , R 2 and R 3 are independently hydrogen, a C 1 -C 20 alkyl group, a C 1 -C 20 alkoxyphenyl group or a phenyl group Yes; and R 4 and R 5 are C 1 -C 20 alkyl groups, A conjugated polymer with perylenetetracarboxylic acid diimide and benzodithiophene, a method for preparing the same, and use thereof are provided. The conjugated polymer has good solubility, strong absorbance, wide light absorption range, improved photoelectric conversion efficiency, and excellent charge transport performance, thereby enabling solar cells, organic electroluminescent devices and organic field effects It can be widely used in the field of photoelectric energy conversion such as transistors. |
