METHOD FOR PREPARING ORGANIC, IN PARTICULAR LITHOCHOLIC ACID, NANOTUBES AND USES THEREOF

摘要

The invention concerns a method for preparing organic nanotubes in aqueous medium, comprising the following steps: a) preparing a basic aqueous solution having a pH of 10 to 14, preferably 12 to 13.5; b) adding to the solution a compound of formula (I), wherein: R<1> is a polycyclic radical with condensed C17-C20 rings optionally comprising alkyl substituents; R<2> is a linear or branched C3-C20 alkylene group; and R<3> represents a hydrogen atom, a C1-C20 alkyl group or a C6-C30 aromatic group; and c) stirring the solution for a time interval sufficient to form stable tubules of the organic compound in the solution. The organic compound may be lithocholic acid.
