    Abstract

    Radical reactions of various radical initiators in liquid phase were carried out to investigate the reactivity of hydrogenated diamond surface. Benzophenone, which is one of the most popular photosensitizers, and AIBN (α,α′-azobisisobutyronitrile), which is one of the most popular radical initiators of azo compounds, could not abstract hydrogen atoms on the diamond surface. On the other hand, benzoyl peroxide, which is one of the most popular radical initiators of peroxides, could abstract the hydrogen atoms on a diamond surface. From the results of this study, it was found that the reactivity for the hydrogen abstraction reaction with organic radical reagents depends on the kind of the radical species.
