Abstract
Supramolecular polymers are described that are derived from the association of two homoditopic heterocomplementary monomers through sextuple hydrogen‐bonding arrays. They form fibers and a variety of different materials depending on the conditions. The strong affinity of the DAD–DAD (D=donor, A=acceptor) hydrogen‐bonding sites for double‐faced cyanuric acid type wedges drives the supramolecular polymeric assembly in apolar and chlorinated organic solvents. The marked influence of stoichiometry, as well as end‐capping and cross‐linking agents upon fiber formation is revealed in solution and by electron microscopy (EM). The results further contribute to the development of a supramolecular polymer chemistry that comprizes reversible polymers formed through recognition‐controlled noncovalent connections between the molecular components. Such materials are, by nature, dynamic and present adaptive character in view of their ability to respond to external stimuli.Keywords
