Abstract Cyanation is a common chemical modification strategy to fine‐tune the energy levels and molecular packing of organic semiconductors, especially materials used in solar cells (OSCs). Generally, cyanation modify end groups high‐performance small‐molecule acceptors (SMAs). However, has not been investigated on central backbone SMAs, which could introduce stronger intermolecular interaction enhance π–π stacking for rapid charge transport. This paper, first time, reports new...
Two star-shaped helical perylene diimide (PDI) electron acceptors TPDI2 and FTPDI2 were designed synthesized for nonfullerene organic solar cells (OSCs). The integration of PDIs into a three-dimensional structure provides new strategy to tune the intermolecular interactions, as-cast blend films with PTB7-Th show favorable morphology as well efficient charge transfer separation, evidenced by femtosecond transient absorption (fs-TA) spectroscopy studies. A trade-off between suppressing...
