Heteroleptic platinum(II) complexes find wide application in supramolecular and photochemistry. Nevertheless, efficient methods for their preparation are limited. Herein, we report a novel synthetic approach toward heteroleptic trans‐bis(iminopyrrolyl)Pt(II) complexes with N‐propyl, ‐pentyl, ‐methoxyethyl, and ‐phenyl substituents using a Zeise's dimer analog as the platinum source. The developed route, which consists of two sequential complexation reactions with the corresponding sodium salt of the iminopyrrolyl ligand, is operationally simple and delivered the mono and trans‐bis coordinated products quantitatively and highly stereoselectively. The obtained Pt(II) complexes exhibited crystallization‐induced phosphorescent emission enhancement behavior. Furthermore, the luminescence properties were dependent on the substituents on the nitrogen atoms of the iminopyrrolyl ligands. Hence, this study is expected to have important implications in the fields of supramolecular and photochemistry.

有效的立体选择性合成和具有双齿亚氨基吡咯基配体的方平面铂（II）配合物的光学性质。

异铂（II）配合物在超分子和光化学中得到广泛应用。然而，有效的制备方法受到限制。本文中，我们报道了一种新的合成方法，该方法使用Zeise的二聚体类似物作为铂源，对具有N-丙基，-戊基，-甲氧基乙基和-苯基取代基的杂合反式-双（亚氨基吡咯基）Pt（II）配合物进行了研究。所开发的路线由两个顺序的与亚氨基吡咯烷基配体的相应钠盐进行的络合反应组成，操作简单，可单价或反价‐bis定量和高度立体选择性地协调产品。获得的Pt（II）配合物表现出结晶诱导的磷光发射增强行为。此外，发光性质取决于亚氨基吡咯基配体的氮原子上的取代基。因此，这项研究有望在超分子和光化学领域产生重要意义。
