A series of novel long-wavelength, fluorescent, novel iminocoumarin derived dyes were synthesized by extending the π-conjugation and spatial location of the benzimidazolic and iminochromene rings in a planar structure. Several dyes display a fluorescent maxima ≥600 nm whilst others showed fluorescent maxima in the NIR region.
