Electron-accepting pi-Conjugated Systems Based on Cyclic Imide and Cyano-substituted Benzothiadiazole for Non-fullerene Organic Photovoltaics

摘要

To develop organic semiconductors for the application to acceptor materials in organic photovoltaics, we synthesized new pi-conjugated compounds consisting of cyclic imide and cyano-substituted benzothiadiazole. Photophysical and electrochemical properties as well as semiconducting performance of these compounds were investigated.
