正方形平面铂（II）配合物通过自组装或配体桥联而堆叠时通常表现出强烈的颜色和发光。颜色和发光的起源是金属-金属电子相互作用，因此，颜色的显著变化（即，变色）是通过控制Pt中心点Pt相互作用而预期的。组装的复杂系统的分子排列对环境因素如温度、压力、溶剂和蒸气敏感。该帐户的重点是发光铂（II）配合物与2，2 '-联吡啶或其衍生物对环境的传感功能。特别是，由蒸汽分子引起的发光变化将从化学传感的角度进行检查。单核和双核铂（II）配合物的汽色行为和结构方面进行了讨论。
Square-planar platinum(II) complexes often exhibit intense color and luminescence when they are stacked via self-assembly or bridging by ligands. The origin of the color and luminescence are the metal-metal electronic interactions, and thus, remarkable changes in color (i.e., chromism) are expected by controlling the Pt center dot center dot center dot Pt interactions. The molecular arrangement of the assembled complex systems is sensitive to environmental factors such as temperature, pressure, solvent, and vapor. This account focuses on the sensing functionalities of luminescent platinum(II) complexes with 2,2'-bipyridine or its derivatives toward their environment. Especially, luminescence changes that are induced by the vapor molecules will be examined from the viewpoint of chemical sensing. The vapochromic behavior and structural aspects of the mononuclear and dinuclear platinum(II) complexes are discussed.
