摘要

A new fluorinated pyran-bridged A-D-A type small molecular non-fullerene acceptor, i-PTIC-F, is designed and synthesized. The optical and electrochemical properties have been well studied and compared with the non-fluorinated molecule, i-PTIC. The photovoltaic performance of i-PTIC-F is characterized using PBDB-T as the donor material. A reasonable power conversion efficiency of 5.68% is achieved with an enhanced Jsc of 14.56 mA cm−2.
