摘要：

Coumarin-30 and its regioisomer 7-(diethylamino)-4-(1-methyl-1H-benzimidazol-2-yl)coumarin were synthesised utilising condensation of the corresponding formylcoumarin with N-methylphenylene-1,2-diamine as the key step. Furthermore, absorption and fluorescence emission spectra of the two coumarins were recorded.
