NEW P-TYPE LOW BANDGAP POLYMERS AND THEIR USE

摘要

Synthesis of a benzothiadiazole/thiophene-based oligomer/polymer for bulk heteroj unction photovoltaic cells. The polymer/oligomer comprises electron donating units such as fluorene, dibenxothiophene, dibenzosilole dihydroindenofluorene etc and electron withdrawing units such as benzothiadiazole and is represented by formula (I).
