Novel quaternary ammonium cationic gemini surfactants,with two hydrocarbon chains and an adamantane core,were designed and synthesized by three-step reactions from adamantane.The structure of obtained surfaaants were confirmed by ~1H NMR,FTIR and elements analysis and the surface properties of these surfactants were also studied by surface tension measurements.These target surfactants exhibit much lower critical micelle concentrations(CMC) and higher efficiency in lowering the surface tension of water than typical surfactants.
