Abstract
Triisopropylethynyl derivatives of pentacene (TIPSEP) and anthradithiophene (TIPSEAdT) copolymerized with diethynylbenzene and fluorene via Sonogashira and Suzuki coupling show optical bandgaps between 1.6 and 2.0 eV. TIPSEAdT-9,9-dioctylfluorene yielded preliminary photovoltaic power conversion efficiency of 0.69%. Article not available.
