In this article we examine the effect of molecular shape on the formation of thermotropic phases of alkyl-substituted poly-ols. The relationship between the cross-sectional area of the hydrophilic head group with respect to the that of the hydrophilic tails determines the type of mesophase formed. The results obtained are similar to those found for the formation of lyotropic phases.

This invention relates to cationic lipids. More particularly the invention relates to biodegradable cationic lipids having a plurality of cationic headgroups and one or more lipophilic tail groups. The lipids are of utility in various applications, and in particular in permitting transfection of molecules, and in particular DNA and RNA, into cells. As such the lipids have specific utility in the field of gene therapy as well as other applications such as delivery of small molecules into cells, detergents, and metal ion complexation for medical or industrial applications.
