Abstract
The invention relates to a method for preparing organic nanotubules in an aqueous medium, comprising the following steps: a) preparing a basic aqueous solution with a pH from 10 to 14, preferably from 12 to 13.5, b) adding to the solution an organic compound of formula: 1 wherein R1 is a C17-C20 polycyclic radical with fused rings optionally including alkyl substituents, R2 is a C3-C20 linear or branched alkylene group, and R3 represents a hydrogen atom, a C1-C20 alkyl or C6-C30 aromatic group, and c) submitting the solution to stirring for sufficient time in order to form stable tubules of the organic compound in the solution. The organic compound may be lithocholic acid.
