Abstract
Surface active materials including surfactant are the substances that exert a variety of functions at the interface, and so the relationship between their chemical structures and performance is very important in practical as well as academic. In this article, to control the orientation of the Rf groups on the surface with close packing, the author raised a novel concept of introduction of fluoroalkyl groups (Rf) as both (i) semifluoroalkyl (semi-Rf) and (ii) multi-chain structure, and also outlined his research results on the development of Rf end-capped oligomeric interface materials, surface modifying polymer having double semi-Rf groups into the side chains, and semi-Rf based Gemini surfactants. Furthermore, as the environment friendly surfactants, the development of corynomycolic acid and Gemini surfactants are described as well as the effects of stereochemistry in the succinic Gemini and tartaric Gemini on their functional properties.
