Abstract:
Metal-ligand binding plays a crucial role in regulating the photophysical properties of supramolecular gels. In this study, we designed 1-Pt complexes comprising a central benzene-1,3,5-tricarboxamide unit functionalized with three terpyridines, which can form supramolecular gels with Pt(II). The resulting supramolecular gel of 1-Pt exhibited strong orange emission, which was attributed to the metal-to-metal ligand charge transfer during gel formation. Furthermore, the temperature-dependent absorption spectrum changes of the supramolecular polymer 1-Pt exhibited a nonsigmoidal transition, following a cooperative pathway involving a nucleation-elongation mechanism. Additionally, the strategy for the co-assembling system involving 1-Pt with chiral molecules (D-form and L-form) induced the helical arrangement of 1-Ptvia chiral additives in supramolecular metallogels.
