Pt complexes of π-extended dipyrrolyldiketones were synthesized as anion-responsive π-electronic molecules. The dipyrrolyldiketone Pt complexes exhibited red-shifted absorption and photoluminescence properties. In the solid state, [1 + 1]-type anion complexes formed charge-by-charge ion-pairing assemblies when combined with countercations. Detailed theoretical studies of the packing structures revealed favorable interactions between the planar anion complexes and π-electronic cations.
π-扩展二吡咯二酮的铂配合物被合成为阴离子响应性π电子分子。二吡咯二酮铂配合物表现出红移吸收和光致发光特性。在固态中，[1 + 1]型阴离子配合物与抗衡阳离子结合时形成逐电荷的离子对组装体。对堆积结构的详细理论研究揭示了平面阴离子配合物与π电子阳离子之间的有利相互作用。
