Abstract

Abstract Thieno [3, 4-c] pyrrole-4, 6-dione-based organic sensitizers with triphenylamine (FNE38 and FNE40) or julolidine (FNE39 and FNE41) as electron-donating unit have been designed and synthesized. A linear hexyl group or a branched alkyl chain, the 2-ethylhexyl group, is incorporated into molecular skeleton of the dyes to minimize intermolecular interactions. The absorption, electrochemical, and photovoltaic properties for these ...
