合成双分子膜三元体系的激发态能量转移

Ternary Energy Transfer from Titan Yellow Cascading through Fluorescein Sodium to TPPS 4 in Synthetic Bilayer Membranes

在４（４’癸氧基４氧基联苯）丁基三甲基溴化铵双分子膜体系内，通过静电相互作用使达旦黄、荧光黄和四苯基卟啉磺酸阴离子键合在囊泡表面；研究了达旦黄给体通过荧光黄传递到四苯基卟啉磺酸阴离子受体的三元激发态能量转移。能量转移的结果改善了光的输出，扩展了光波的输出范围。

Ternary excitation energy transfer from titan yellow donor cascading through fluorescein sodium to tetraphenyl porphin acceptor, with all molecules anchored on the surface of bilayer membranes by electrostatic effect, were studied in the mixture system of DBBTAB 4 (4’ decyloxy 4 biphenyloxy) butyltrimethyl ammonium bromide vesicles. The efficient energy transfer improved the light efficiency and extended the spectral response region. The experimental resules imply that DBBTAB vesicle is a promising efficient medium for dye laser.
