NEW FLUORESCENT 2-(5-ACETOACETYL-2-FURYL)- BENZAZOLES WITH PROCHIRAL METHYLENE GROUP PROTONS

Abstract

New fluorescent benzazoles containing prochiral protons in the methylene group have been synthesized. Their spectral-absorption and fluorescent properties have been investigated. Quantum yields of fluorescence were 0.39–0.55. The long-wave absorption band and the emission band in the spectra of the obtained acetoacetyl furylbenzazole derivatives are caused by electronic transition with charge transfer between the benzazole and acetoacetylfuryl fragments.
