Cooperative self-assembly and gelation of organogold(I) complexes via hydrogen bonding and aurophilic Au⋯Au interactions

With the synergistic combination of intermolecular Au(I)–Au(I) and hydrogen bonding interactions, a rod–coil alkynyl–gold(I)–isocyanide monomer tends to form supramolecular fibers and gels via a cooperative nucleation–elongation self-assembly mechanism, which display Ag(I) ion-triggered responsiveness.
