Exploration of a proquinoidal [1,2,5]thiadiazolo[3,4-g]quinoxaline-based small molecule acceptor toward high-sensitivity shortwave infrared photodetection

A novel small molecule acceptor (TQpp) was developed for VIS-SWIR broadband photodetection. The TQpp-based device achieves 18.4% EQE and 1×10¹² Jones at 1100 nm, enabling high-precision real-time pulse monitoring under ultralow 1064 nm illumination.
