Photopolymerization of self-organizing ionic liquids.

In this article we describe the photo-initiated cyclopolymerization of N,N-diallyl-N-dodecylammonium chloride and N,N-diallyl-N-hexadecylammonium chloride in aqueous lyotropic mesophases using a low power UVA domestic sunlamp to produce anisotropic polymers. We further demonstrate the formation of cross-linked anisotropic polymer networks upon the addition of 1,8-bis-(N,N-diallylammonium)octane chloride.

Syntheses, amphitropic liquid crystallinity, and surface activity of new inositol-based amphiphiles.

Carbohydrates are interesting starting materials for scientific and industrial syntheses as they allow a versatile chemistry. Moreover, they are of natural origin and environmentally benign. During the past few years, inositol, a rather "exotic" carbohydrate, and its derivatives have gained increasing attention. Here, we describe the syntheses of new regiochemically defined inositol monoethers and monoesters as well as regioisomeric inositol ester mixtures and investigate their amphitropic liquid crystallinity. Furthermore, first results on their surface activity in aqueous solutions are given and compared with classical sugar surfactants.
