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.

本研究观察到一系列新合成的、以第三配位模式存在的bis(salicylaldiminato)铂(II)配合物，其在晶体状态下展现出前所未有的强烈磷光发射。本通讯详细描述了这些配合物在液态和晶体状态下的动态光物理性质，并对其在晶体状态下强发射的机理进行了深入探讨。
