以聚醚链相连的9-氨基吖啶、苯甲酸酯二元体系的合成及分子内光诱导电子转移反应

SYNTHESIS OF POLY(ETHYLENE GLYCOL)LINKEDDONORACCEPTOR SYSTEMS AND INVESTIGATION OF INTRAMOLECULAR ELECTRON TRANSFER

本文用聚四乙二醇柔性链将９－氨基啶和不同取代基的苯甲酸酯连接起来，合成了一类新型二元分子体系。对各体系中９－氨基啶的电子转移荧光猝灭进行了研究，并根据稳态荧光猝灭计算了体系中的荧光猝灭效率和荧光猝灭速率常数。

 series of electron donoracceptor system linked by polyethylene glycol have been synthesized. The electron transfer fluorescence quenching of 9aminoacridin was investigated, efficiencies and rate constants of electron transfer fluorescence quenching have been calculated. 
