In this study, we developed a series of novel non-fullerene acceptors (NFAs) incorporating quinoidal core, which are thienothiophenedione and benzodithiophenedione, aiming at organic photodetectors (OPDs) capable of detecting short-wavelength infrared (SWIR) light. All synthesized acceptors exhibited distinct optical absorption in the SWIR region. Notably, the acceptors containing the benzodithiophenedione unit showed significantly extended absorption, reaching wavelengths of up to 1500 nm. In this presentation, we discuss the molecular design and synthesis of NFAs, as well as their optical properties and OPD device performance.
