Highly Phosphorescent Crystals of Vaulted trans-Bis(salicylaldiminato)platinum(II) Complexes

Unprecedented strong phosphorescent emission in the crystalline state is observed for a variety of vaulted trans-bis(salicylaldiminato)platinum(II) complexes which are newly synthesized as a third coordination mode of well-studied bis(salicylaldiminato) complexes. This Communication describes the dynamic photophysical properties of these complexes in the liquid and crystalline states and a mechanistic rationale for the strong emission in the crystalline state.

在众多新合成的、以已研究过的双(水杨醛二肟)铂(II)配合物为第三配位模式的拱顶式双(水杨醛二肟)铂(II)配合物中，观察到前所未有的强磷光发射。本通信描述了这些配合物在液态和结晶态下的动态光物理性质，以及结晶态中强发射的机理阐释。
