Gelation by supramolecular dimerization of mono(urea)s?
Chemical Communications Pub Date: 2015-10-30 DOI: 10.1039/C5CC06995E
Abstract
Mono-ureido salicylic acid derivatives form hydrogen bonded dimers that mimic the gelation behaviour of covalently linked bis(urea)s. The 5-ureido salicylic acid isomers are much more effective gelators because of the lowered conjugation and less planar geometry, resulting in stronger urea?urea α-tape hydrogen bonding interactions.
