Title:
A-D-A CONJUGATED MOLECULE, PREPARATION METHOD THEREFOR, USE THEREOF IN ORGANIC SOLAR CELL, AND ORGANIC SOLAR CELL
Document Type and Number:
WIPO Patent Application WO/2021/037278
Kind Code:
A1
Abstract:
Provided are an A-D-A conjugated molecule, a preparation method therefor, an organic solar cell, and the use of the A-D-A conjugated molecule in an organic solar cell. The A-D-A conjugated molecule has the following general structure: (I), wherein R1 is 4-alkylphenyl, 4-alkoxyphenyl, 4-alkylthiophenyl, 4-alkylthienyl, 4-alkoxythienyl, 4-alkylthiothienyl, 4-alkylselenophenyl, or 4-alkylthioselenophenyl; Ar is a thiophene group, a thiophene derivative group, a fused-dual-thiophene group, a fused-dual-thiophene derivative group, a fused-triple-thiophene group, a fused-triple-thiophene derivative group, a benzodithiophene group, a benzodithiophene derivative group, a pyrrolodithiophene group, a pyrrolodithiophene derivative group, a pentane fused-dual-thiophene group, or a pentane fused-dual-thiophene derivative group; and EG is a capping group. The present invention has a stronger light absorption capacity, a better charge transfer performance, and a suitable electronic energy level.
