Abstract

A study was conducted to prepare a A thieno[3,4-c]pyrrole-4,6-dione (TPD)-based donor-acceptor polymer exhibiting high crystallinity for photovoltaic applications. A new D-A polymer, called PBTTPD was prepared wherein the electron-withdrawing TPD unit was conjugated with the symmetrical electron-donating bi(dodecyl)thiophene unit to provide crystalline characteristics and a low-lying HOMO energy level, resulting from the combination of the rigidly fused TPD moiety and the symmetrical bi(dodecyl)thiophene units. The polymer was prepared through stille polymerization of themonomers 1,3-dibromo-5-ethylhexylthieno[3,4-c]pyrrole-4,6- dione (M1) and 4,40-didocecyl-5,50-bis(trimethylstannyl)-2,20-(M1) and 4,4'-didocecyl-5,50-bis(trimethylstannyl)-2,2'-bithiophene (M2) using tris(dibenzylideneacetone)dipalladium/tri-(o-tolyl)phosphine [Pd 2dba3/P(o-tolyl)3] as the catalyst.
