Abstract
A new discrete supramolecular metallacage functionalized with an alkynylplatinum(ll) 2,6-bis(benzimidazole-2'-yl)-pyridine (bzimpy) moiety has been successfully constructed via coordination-driven self-assembly. A study on the hierarchical self-assembly behavior of the obtained metallacage revealed that it displayed a solvent-induced emission switch accompanied by enhancement of the emission intensity as a result of the change in intermolecular Pt···Pt and π-π interactions. More interestingly, the metallacage has been found to spontaneously self-assemble into a transparent metallogel at room temperature without a heating-cooling process.
