Some fluorescent benzimidazole derivatives have been designed and synthesized using cobalt(II) hydroxide as highly efficient catalyst. Synthesized compounds have been characterized by 1H and 13C-NMR and mass spectral anal. The solvent effect on the absorption and fluorescence bands has been analyzed and supplemented by computational studies. Solvatochromic effects on the spectral position and profile of the stationary fluorescence spectra clearly indicate the charge transfer (CT) character of the emitting singlet states of all of the compounds studied in both polar and non-polar environments. The fluorescence decays for the benzimidazoles fit satisfactorily to a single exponential kinetics. HOMO and LUMO orbital pictures [DFT/B3LYP/6-31G(d,p)] evidence the existence of excited state intramol. proton transfer (ESIPT) in benzimidazole derivatives containing a hydroxy group.
