摘要：

A small-molecular acceptor, tetraphenyl-pyrazine-perylenediimide tetramer (TPPzPDI 4), which has a reduced extent of intramolecular twisting compared to two other small-molecular acceptors is designed. Benefiting from the lowest extent of intramolecular twisting, TPPz-PDI 4 exhibits the highest aggregation tendency and electron mobility, and therefore achieves a highest power conversion efficiency of 7.1%.
