Ionic Liquid Type Surfactants

N’N-Dimethyl Derivative of Amino Alcohol

The term ionic liquids (ILs) type

surfactants is referred to a class of

compounds that are not only ILs at

room temperature, but also consisting

of hydrophobic sites and polar head

groups forming micelles or molecular

micelles upon polymerization. We have

successfully exploited these unique structural tendencies by preparing IL micelle forming surfactants

with five different chiral head groups (see above) for applications in separation science.
