A New Strategy To Form Multicompartment Micelles: Fluorocarbon-Hydrocarbon Ion-Pair Surfactant

The hydrophobic core of the multicompartment micelles consists of incompatible and clearly separated distinct subdomains which make them different from the classical micelles. Owing to these properties multicompartment micelles have a great potential to be used as solubilization agents and carriers fora wide variety of applications where it is important to prevent the uncontrolled interaction of the solubilizates before reaching the target and to convey them to the specified point simultaneously. Here we show that effective compartmentalization inside the micelle and high solubilization capacity for the two immiscible water-insoluble materials in cases of both simultaneous and separate solubilization can be achieved by newly designed ion-pair hybrid surfactant CH3(CH2)(11)(OCH2CH2)(23)N+(C2H5)(3-) SO3-(CF2)(7)CF3 (C12E23N+SO3-F8) through the agency of favorable molecular design. Molecular structure is tailored by the approach of using a balance of forces to obtain compartmentalization, which is without precedent. This new molecule also has the properties of quite low critical micelle concentration and an extensive surfactant concentration range for solubilization which are additional important advantageous features.
