title: Donor-acceptor polymers based on multi-fused heptacyclic structures: synthesis, characterization and photovoltaic applications.
abstract: We report here two novel 2,7-fluorene- and 2,7-carbazole-based conjugated polymers PFDCTBT and PCDCTBT containing ladder-type heptacyclic structures with forced planarity. PCDTBT shows excellent solubility, low band gap and high hole mobility, leading to a power conversion efficiency of 3.7%.
