Abstract
Abstract We describe synthesis and fluorescence properties of phenyl and styryl p-disubstituted fluorescein. The compound was synthesized in three reaction steps from trans,trans,trans-1,6-diphenyl-1,3,5-hexatriene. The fluorescence spectrum of the product in alkaline methanol solution suggested occurrence of intramolecular FRET from the donor site of the benzene moiety to the acceptor site of the xanthene moiety.
