Abstract利用激光光解装置检测了C60-地塞米松(C60-DE)的苯溶液在355nm激光照射下产生的激发三重态,3C60-DE*出现四个吸收峰,分别位于700、440、350和310nm.在330nm处观察到了它的漂白吸收最大值,这与其基态吸收最大值相对应.3C60-DE*能够将能量转移给O2分子而淬灭.与3C60*相比,3C60-DE*的三重态-三重态(T-T)淬灭速率常数减小(3C60*为(5.03±1.31)×109L·mol-1·s-1,3C60-DE*为(3.53±0.87)×109L·mol-1·s-1),而寿命增加了(3C60*为(12.0±2.6)!s,3C60-DE*为(18.0±3.3)μs),这可能是C60分子上连接了地塞米松分子后减小了C60球之间碰撞的几率所致.
