CO-POLYMER OF 2,7-CARBAZOLE AND DITHIENYL THIAZOLOTHIAZOLE, AND METHOD FOR PREPARING SAME AND SOLAR BATTERY CONTAINING SAME

摘要

Provided are a co-polymer of formula (I) of 2,7 -carbazole and dithienyl thiazolothiazole, a method for preparing same, and a solar battery containing same. The structural formula of the co-polymer of 2,7 -carbazole and dithienyl thiazolothiazole is as shown by formula (I), wherein both R 1 and R 2 are C 1 -C 20 alkyl groups, and n is an integer of 10-100. The co-polymer of the present invention has a novel structure, a good dissolving property, an excellent film-forming property, and a high power conversion efficiency, and can be used as the material for a solar battery. Also provided are the method for preparing the co-polymer and the solar battery containing same. The preparation method uses raw materials widely available and has a simple synthesis route.
