摘要

用时间分辨激光光解技术对富勒烯水溶性衍生物C,70,富勒醇[C,70,（OH）,m,]研究发现，与通常富勒烯衍生物，如C,60,[C（COOEt）,2,],n,C,60,（C,4,H,6,O）, C,60,（C,3,H,7,N）在溶液中光解常产生激发三重态不同，C,70,富勒醇能被248nm激光单光子电离。以KI溶液为参照，测定其水合电子的量子产额（Ф,e-,）为0.11。将激光光解与,http://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=42489881&type=,http://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=42489900&type=,http://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=42489897&type=,的氧化对比，确认了到C,70,富勒醇阳离子自由基的吸收峰。

Abstract

Using time-resolved laser photolysis techniques, it has been demonstrated that fullerol of C,70,unlike some other fullerene derivatives, does not result in excited triplet state but in ionization via monophotonic process with 248 nm laser. The quantum yield of formation of hydrated electrons (Φ,e-,) is determined at room temperature (about 15℃) in neutral aqueous solution with KI solution used as reference. The fullerol radical cation of C,70, is observed for the first time by laser photolysis or oxidation of sulfate radical anion ,http://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=42489913&type=,http://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=42489901&type=,http://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=42489916&type=, in aqueous solution.
