摘要：

Some novel benzimidazole derivatives were synthesized and characterized by H-1, C-13 NMR mass and elemental analysis. XRD analysis was carried out for 1-(4-methylbenzyl)-2-p-toly1-1H-benzo[d]imidazole. The solvent effect on the absorption and fluorescence bands has been analyzed. The energetic analysis of the potential energy surface (PES), HOMO and LUMO levels [DFT/B3LYP/6-31G(d,p)] evidenced the existence of excited state intramolecular proton transfer (ESIPT) in hydroxy benzimidazole derivative.
