説明
<jats:title>Abstract</jats:title><jats:p>A variety of π‐electronic ion‐pairing assemblies can be constructed by combining anion complexes of π‐electronic systems and countercations. In this study, a series of anion‐responsive π‐electronic molecules, dipyrrolyldiketone Pt<jats:sup>II</jats:sup> complexes containing a phenylpyridine ligand, were synthesized. The resulting Pt<jats:sup>II</jats:sup> complexes exhibited phosphorescence emission, with higher emission quantum yields (0.30–0.42) and microsecond‐order lifetimes, and solution‐state anion binding, as revealed by our spectroscopic analyses. These Pt<jats:sup>II</jats:sup> complexes displayed solid‐state ion‐pairing assemblies, exhibiting various anion‐binding modes, which derived from pyrrole‐inverted and pyrrole‐non‐inverted conformations, and packing structures, with the contribution of charge‐by‐charge assemblies, which were dependent on the substituents in the Pt<jats:sup>II</jats:sup> complexes and the geometries and electronic states of their countercations.</jats:p>
