Abstract
A series of clickable single-benzene-based fluorophores derived from tetrafluoroterephthalonitrile (4F-2CN) is reported. Fluorophores based on a tetrahydroquinoxaline skeleton (2F-2CN-(β-NH2Ala)) exhibited improved photophysical properties owing to better planarity and conjugation over those with dihydro[1,4]thiazine skeleton (2F-2CN-Cys). These easily produced clickable fluorophores were successfully applied in in vitro and in vivo bioimaging after protein conjugation.
