photostable fluorescent markers with large fluorescence quantumyields, low dark triplet state population, good biocompatibility and absorption and emission maxima in the near-infrared, where cellular autofluorescence is minimized. In the present study, carbopyronines absorbing around 640 nm and emitting at around 660 nm, with a low intersystemcrossing rate (kisc ≈ 0.5 e6/s) and excellent properties for
