摘要：
A Pt(II) phenylbipyridine complex 1, possessing phenylisoxazoles, long alkyl chains, and chiral alkyl chains, was synthesized. Complex 1 formed a stacked assembly in chloroform, self-assembled in a cooperative manner in methylcyclohexane (MCH), and gelled in higher alcohols and dodecane. In the nucleation regime, 1 assembled via a Pt-Pt interaction, which was demonstrated by the metal-metal-to-ligand charge transfer (MMLCT) emission band of the assembly. In the elongation regime, 1 displayed aggregation-induced emission enhancement (AIEE) character. The assembly of 1 formed in MCH was chiroptically non-active, suggesting that the assembly was non-helical. Complex 1 also exhibited strong AIEE and circularly polarized luminescence (CPL) with an anisotropic factor (glum) of 0.011 in 1-decanol gel, indicating that a chiral assembly was formed in the gel.
