  Synthesis, spectroscopic and DFT studies of novel fluorescent dyes: 3-Aminoimidazo[1,2-a]pyridines possessing 4-pyrone moieties

  摘要：

  A series of novel imidazo[1,2-a]pyridines possessing 4-pyrone ring were synthesized by three-component condensation of 4-pyrone carbaldehydes, 2-aminopyridines and isocyanides. Bismuth (III) chloride was used as a catalyst in these reactions and desired products were synthesized in good yields at a very short period of time under solvent free conditions. UV-Vis absorption and fluorescence emission spectra of these compounds were investigated. It shown that two of these compounds (10f and 10g) exhibit intense fluorescence in dichloromethane. Optimized ground-state molecular geometries and orbital distributions of these two fluorescent dyes were obtained using density functional theory (DFT). Thermogravimetric analysis and electrochemical properties of these compounds were also studied. (C) 2013 Published by Elsevier B.V.
