摘要:

Fluidity of nonionic surfactant assembly formed at the silica-water interface was investigated on the basis of intramolecular excimer formation dynamics of 1,3-bis(1-pyrenyl)propane. It was found that the rate constant of intramolecular excimer formation is almost independent of the adsorption density of surfactant molecules. These results imply that local structure of hydrocarbon region in surfactant assembly is almost unchanged in a wide range of adsorption density, although whole structure of the assembly varies with the adsorption density at the interface.
