Four novel azo derivatives of indolizine were synthesized and fully characterized by ¹H and ¹³C NMR,FTIR,elemental analysis,and thermal analysis.The behaviour of these diazo dyes in various solvents was evaluated.Substituent,acid and base effects on the visible absorption maxima of the dyes were also reported.The absorption maxima displayed a blue-shift when the compounds were present under ionic condition.DSC curves show that the decomposition temperature for the compound having alkyl substituent at the C-2 position is 180 ℃.2-Phenyl-substituted compounds are comparatively stable,with a decomposition temperatures above 200 ℃.
