A series of novel long-wavelength, fluorescent, novel iminocoumarin derived dyes were synthesized by extending the pi-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. (C) 2009 Elsevier Ltd. All rights reserved.
