title: β-Thiophene-fused BF2-azadipyrromethenes as near-infrared dyes.
abstract: A facile synthetic route to a new class of near-IR β-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.
