Abstract
Abstract Novel 6,7-diamino-4-methylcoumarin and derived imidazolocoumarins were synthesized and their absorption and fluorescence properties were recorded in solvents of varying polarity. 6,7-Diamino-4-methylcoumarin is highly fluorescent, with a quantum yield of 0.78 in dioxane. The fluorescence intensity of 6,7-diamino-4-methylcoumarin, when mixed with different carbonyl group containing compounds, decreased. Based on the interaction of this diaminocoumarin with the carbonyl compound a fluorescent sensor with high selectivity towards electron rich benzaldehydes and cinnamaldehyde was developed.
