Facile Synthesis and Fluorescent Properties of Coumarin-7 and its Isomer 4-(2-Benzimidazolyl)-7-(Diethylamino)Coumarin

Coumarin-7 and its isomer 4-(2-benzimidazolyl)-7-(diethylamino)coumarin were synthesised using condensation of the corresponding formylcoumarin with o-phenylenediamine as the key step. Moreover, absorption and fluorescence emission spectra of these two coumarins were recorded.
