A cyanurate gel derived from two different hydrogen-bonding interactions in a binary system: evidence for the driving forces in gel formation

A cyanurate derivative (1) possessing three carboxylic acid groups forms a two-component supramolecular hydrogel in the presence of 4,4-bipyridine (2) by intermolecular hydrogen-bonding interactions between –CH of 4,4-bipyridine (2) and –CO of cyanurate (1) as well as between the N atoms of 2 and –COOH of 1.
