Hierarchical self-assembly of discrete organoplatinum(II) metallacycles has attracted considerable attention. However, the exact assembly mechanism involving non-covalent interactions has limited the formation and application of self-assembly due to the dynamics of platinum metallacycles. Herein, we report the hierarchical self-assembly of a pyrene-based discrete organoplatinum(II) double-metallacycle that takes advantage of heteroligation-coordination-driven self-assembly and triflate anions' hydrogen bonding, which is extended into a 3-D supramolecular framework by the hydrogen-bonding interactions involving triflate anions. Furthermore, the assembled system displays tunable fluorescence emission and enhanced solid emission. The studies herein disclosed pave the way to prepare platinum(II) metallacycle-based supramolecular functional materials.

具有三氟甲磺酸根阴离子的芘基离散有机铂（II）双金属环通过氢键的分级自组装及其可调荧光发射

离散有机铂（II）金属环的分层自组装引起了相当大的关注。然而，由于铂金属环的动力学，涉及非共价相互作用的确切组装机制限制了自组装的形成和应用。在此，我们报告了基于芘的离散有机铂（II）双金属环的分层自组装，该双金属环利用了异位配位驱动的自组装和三氟甲磺酸阴离子的氢键，将其扩展为 3-D 超分子由涉及三氟甲磺酸根阴离子的氢键相互作用构成的框架。此外，组装系统显示可调荧光发射和增强的固体发射。
