Abstract: Two new non-fullerene acceptors based on perylene diimide with acetylenic bridges were designed and synthesized employing Stille and Sonogashira coupling reactions as the key steps. Their optical and electronic properties were explored by UV–VIS spectroscopy and cyclic voltammetry, and energies of frontier molecular orbitals were estimated. Their preliminary studies in perovskite solar cells as electron transport materials showed the best power conversion efficiency for photocells of 14.18% value.
