Thiophene π-Bridge Fluorination Enables Conformational Locking and Molecular Packing for High-Performance TPD-Based Nonfullerene Acceptors
Engineering the π-bridge of nonfullerene acceptors (NFAs) is an effective strategy for regulating their optoelectronic properties and molecular packing; however, the influence of thiophene π-bridge fluorination on charge transport and recombination remains insufficiently understood. Here, two thieno[3,4-c]pyrrole-4,6...
