利用激光光解的时间分辨技术，证明了C-60的富勒醇在水溶液中不同于其他一些富勒烯衍生物(如C-60[C(COOEt)(2)](M)，C-60(C4H6O)，C-60(C3H7N))，在紫外光下不会导致激发三重态，而是通过单光子过程电离。哦，。H和e(Aq)(-)用脉冲辐解进行了研究。与之反应的速率常数。哦，。H自由基和e(Aq)(-)分别由650 nm处观察到的物种的聚集动力学和水合电子的衰变来测定。(C)1998爱思唯尔科学有限公司。保留所有权利。
Using time-resolved technique of laser photolysis, it has been demonstrated that fullerol of C-60 in aqueous solution, unlike some other fullerene derivatives (such as C-60[C(COOEt)(2)](m), C-60(C4H6O), C-60(C3H7N)), does not result in excited triplet state but in ionization via monophotonic process under UV light, Studies on the reaction of fullerol of C-60 With the primary irradiated products of water: . OH, . H and e(aq)(-) have been carried out by pulse radiolysis. Rate constants for the reactions with . OH, . H radical and e(aq)(-) have been determined by following the build-up kinetics of the species or the decay bf hydrated electron observed at 650 nm respectively. (C) 1998 Elsevier Science Ltd.
