The invention relates to a method for preparing organic nanotubules in an aqueous medium, comprising the following steps: n a) preparing a basic aqueous solution with a pH from 10 to 14, preferably from 12 to 13.5, n b) adding to the solution an organic compound of formula: n n n wherein R 1 is a C 17 -C 20 polycyclic radical with fused rings optionally including alkyl substituents, R 2 is a C 3 -C 20 linear or branched alkylene group, and R 3 represents a hydrogen atom, a C 1 -C 20 alkyl or C 6 -C 30 aromatic group, and n c) submitting the solution to stirring for sufficient time in order to form stable tubules of the organic compound in the solution. n The organic compound may be lithocholic acid. |
