PROCEDE DE PREPARATION DE NANOTUBULES ORGANIQUES, NOTAMMENT D'ACIDE LITHOCHOLIQUE, ET LEURS UTILISATIONS

摘要

A method for preparing organic nanotubules in an aqueous medium including preparing a basic solution with a pH from 10 to 14, adding an organic compound of the formula: 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 submitting the solution to stirring for sufficient time in order to form stable tubules of the organic compound in the solution; and nanotubules prepared by the method.
