Dynamic structure of the micelles of gemini alkylammonium surfactants

摘要

The dynamic structure of the micelles of gemini (dimeric) alkylammonium surfactants with different lengths of hydrophobic radicals and polymethylene spacer differing in alkyl substituents of the head group and type of counterion are studied by ESR spin probe technique. The use of probes with different localization of spin moiety makes it possible to quantitatively characterize a decrease in micropolarity when going from the surface of micellar aggregates to the core and compare the dynamic structures of the micelles of dimeric and monomeric analogs.
