Abstract
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.
