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.
我们描述了苯基和苯乙烯基对二取代荧光素的合成和荧光特性。该化合物由反式、反式、反式-1,6-二苯基-1,3,5-己三烯通过三个反应步骤合成。产物在碱性甲醇溶液中的荧光光谱表明,从苯分子的供体位点到氧杂蒽分子的受体位点发生了分子内 FRET。
