Title	The Synthesis and Light Absorption Behaviour of Novel Coumarin Chromophores
Author	Kyoung Lyong An, Seung Rim Shin, Kun Jun, Soo Youl Park*
Keywords	Coumarin, Knoevenagel condensation, Fluorescence, Chromophores
Abstract	The synthetic route to coumarin systems is well established and one approach of particular interest leads to the intermediate 7-diethylamino-3-formylcoumarin. A combination of the N,N-diethylamino-coumarin donor with a wide range of acceptor groups of varying electron withdrawing strength should permit the synthesis of a series of extended coumarin dyes with absorption maxima range from 500 to 600 nm, or even beyond. In this communication, a novel efficient synthesis of indoles, benzothiazole and benzoxazole based on coumarin chromophores were achieved and the coloristic and fluorophoric properties of these chromophores were studied.
