摘要

我们合成了一系列环甲基化（N^C^N）铂(II)-铂配合物，其特点是含有一个非配位氮原子和一个铂-铂键的萜吡啶配体。在 Ag+ 存在下，双（异腈）铂(II)配合物通过 Ag(I) 配位和亲金属的 Pt-Ag 相互作用形成了显著的自组装螺旋状二聚体。在固态下可以观察到其组装，在溶液中也能保持。根据固态 X 射线结构和配位环境，所有复合物都显示出强烈的发光和多种发光状态。

Cyclometalated luminescent platinum(ii) complexes of dissymmetrical 2,2′:4′,2′′-terpyridine and its self-assembled dimer presenting Pt–Ag dative bonds†

A series of cyclometalated (N^C^N) Pt(II)-platinum complexes featuring a terpyridine ligand with a non-coordinating nitrogen atom and a Pt–C bond was synthesized. In the presence of Ag⁺, the bis(isonitrile)Pt(II) complex formed a remarkable self-assembled helicoidal dimer stabilized by coordination of Ag(I) and metallophilic Pt–Ag interactions. Its assembly was observed in the solid state and maintained in solution. All complexes show strong luminescence and multiple emitting states, which could be rationalized based on solid state X-ray structures and coordinating environment.
