摘要
Two exotic non-fullerene acceptors (JX1 and JX2) were effectively developed, and were designed to include, respectively, decameric and dodecameric S,N-heteroacenes. The tandem coupling of electron-donating and electron-deficient moieties on the molecular skeleton enhanced intramolecular charge transfer dramatically, endowing specifically JX2 with excellent absorption of light of low energy approaching 1000 nm. Finally, a JX2-based device outputs a good PCE of 10.83%, providing a rare yet highly promising molecular platform for achieving efficient OSCs with near-infrared-II absorption.
Two exotic non-fullerene acceptors (JX1 and JX2) were effectively developed. The better performance of JX2 with its dodecameric S,N-heteroacene can provide a promising molecular platform for achieving efficient OSCs with near-infrared-II absorption.
