Abstract

Two novel D–π–A–π–D structured small molecules composed of benzothiadiazole and triphenylamine were designed and synthesized. BDCTBT with cyano on the π-bridge exhibited a deep HOMO energy level, resulting in an impressive VOC of up to 1.04 V with a PCE of 3.85%, while non-cyano substituted BDETBT yielded a VOC of 0.94 V and a PCE of 1.99%.
