Lifetime time measurements, Kamlet-Taft and Catalan solvatochromism of some 2-aryl benzimidazole derivatives

Some 2-aryl benzimidazole derivatives (1-6) have been prepared and characterized by different spectral techniques. Fluorescence lifetime of synthesized 2-aryl benzimidazole derivatives was calculated. Kamlet-Taft and Catalan solvatochromism of synthesized 2-aryl benzimidazole derivatives have been discussed. Crystal structure of 1-(4-methylbenzyl)-2-p-tolyl-1H-benzo[d]imidazole has been studied. (C) 2012 Elsevier B.V. All rights reserved.
