A new class of near-infrared (NIR) fluorophores is obtained by consecutive C−N/C−C bond formation between diphenylamines and 9,10-dibromoperylenecarboximide. These fluorophores show high fluorescence quantum yields, together with large Stokes shifts and high photostability, qualifying them as useful NIR emitters for applications as biomarkers and security inks.
