Abstract

Chemical modification of diamond surface with carboxylic acid was attempted by the radical reaction of radical initiator under mild conditions. The peak intensity assigned to the aromatic C-H bond decreased by increasing the number of the benzene ring in carboxylic acid. The number of the carboxylic acid introduced on diamond surface decreased by increasing the number of the benzene ring in carboxylic acid. One of the reasons for this decrement should be the steric hindrance. The zeta potential was not affected by the treatment with the aromatic carboxylic acids. The diamond powders treated with carboxylic acids, which are fluorescent materials, were irradiated with UV light. However, all the samples did not fluoresce because the number of the carboxylic acid introduced on diamond surface is small.
