摘要
A series of novel quaternary ammonium surfactants containing adamantane were designed and synthesized from 1-adamanta- necarboxylic acid. The structures of target surfactants were confirmed by 1H NMR, elements analysis and FFIR. Surface properties of these surfactants were investigated. Due to the lipophilicity of adamantane, the critical micelle concentration （CMC） and C2o values of the synthesized quaternary ammonium surfactants are lower than that of conventional quaternary ammonium surfactants.
