Three component supramolecular assemblies from a mixture of an aromatic donor (D), acceptor (A) and external structure directing agent (ESDA) are achieved by orthogonal noncovalent interactions involving two different types of H-bonding and alternate DâA stacking. An ESDA containing amide or urea produces a chargeâtransfer gel and sol, respectively, owing to their contrasting morphology.
An adaptable and efficient molecularrecognition pair has been established by taking advantage of the complementary nature of donor–acceptor interactions together with the strength of hydrogenbonds. Such distinct molecularrecognition propagates in orthogonal directions to effect extended alternating co‐assembly of two different appended molecular entities. The dimensions of the assembled structures
