摘要：

Benzimidazole derivatives synthesized from three components assembling condensation reaction behaves as a selective fluorescent sensor for Zn2+ metal ion. These benzimidazole derivatives were characterized by H-1, C-13 NMR, mass and elemental analysis. XRD analysis was carried out for 1-(4-methylbenzyl)-2-p-tolyl-H-1-benzo[d]imidazole. The increase in the fluorescence enhancement can be explained on the basis of photo induced electron transfer (PET) mechanism. The blockage of the photoinduced electron transfer process from benzimidazole ring to aryl fluorophore induced by Zn2+ co-ordination induced emission enhancement. (C) 2012 Elsevier B.V.
