Mesoscopic supramolecular assembly of a ‘Janus’ molecule and a melamine derivative via complementary hydrogen bonds

Abstract

Irregular rods with a minimum diameter of ca. 150 Å and lengths of several tens of µm were formed in methylcyclohexane from complementary hydrogen-bond pairs of an alkylalanate-derivatized melamine and a ‘Janus’ molecule; circular dichroism with exciton coupling was induced for the ‘Janus’ chromophore via hydrogen bonds, probably due to the structural regularity of the molecular assembly.
