Large macro-dipoles generated in a supramolecular polymer of N,N′,N-tris(3,7-dimethyloctyl) benzene-1,3,5-tricarboxamide in n-decane

A supramolecular polymer formed by N,N,N-tris(3,7-dimethyloctyl)benzene-1,3,5-tricarboxamide (DO3B) in n-decane (C-10) possesses large macro-dipoles naturally generated by three-fold inter-molecular hydrogen bonding aligned along its helical columnar structure connected by defective portions, which are DO3B molecules containing failure in the hydrogen bond formation, in the order of head to tail arrangement without dipole inversion like type-A polymers.
