A small‐molecular acceptor , tetraphenylpyrazine‐perylenediimide tetramer (TPPz‐PDI 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%.
