本文应用了荧光光谱和时间分辨的荧光光谱技术研究了1,4-二苯乙烯基苯(给体)与吖啶黄(受体)在乙醇的刚性溶液中分子间能量传递的行为, 探讨了分子的浓度、给体、受体分子间的实际距离R、临界距离R0与能量传递效率Er、能量传递速率常数Kr之间的关系.

The intermol. energy transfer between 1,4-distyrylbenzene (donor) and acridine yellow (acceptor) in ethanol rigid solution was investigated by stationary and time-resolved fluorescence techniques. The relationship between energy transfer rate constant KT, energy transfer efficiency ET and the separation of donor and acceptor R0 was discussed according to Foerster's theory of Coulombic energy transfer.
