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.
