Disclosed are a compound represented by Chemical Formula 1, a film, a photoelectric diode, an organic sensor, and an electronic device.
In Chemical Formula 1, Ar1 and Ar2, Z, L1, L2, and R1 to R6 are the same as defined in the detailed description.
A facile synthetic route to a new class of near-IR beta-thiophene-fused BF2-azadipyrromethenes (aza-BDTPs) is presented. Sharp absorption and fluorescence emission bands at around 800 nm were observed for these highly photostable aza-BDTPs, with a large absorption coefficient and very low absorptions in the visible range from 700 to 380 nm.
