Abstract

Cyclometallated platinum(II) complexes with the general formula [Pt(Рpy)(CNR)₂]X (HРpy = 2‑phenylpyridine; R = ⁱPr, ^tBu, Cy; X = BF₄, OTf, PF₆) containing various alkylisocyanide ligands and counterions are synthesized. The compounds are studied by elemental analysis, ESI HRMS, IR spectroscopy, and ¹H, ¹³C{¹H}, and ¹⁹⁵Pt{¹H} NMR spectroscopy. The structures of [Pt(Рpy)(CNⁱPr)₂]BF₄ and [Pt(Рpy)(CN^tBu)₂]BF₄ are determined by XRD (CIF files CCDC nos. 2325595 and 2325527, respectively). The photophysical properties in the solution and in the solid state of the synthesized compounds are studied.

改变铂（II）异氰化物配合物固态发光的结构修饰

合成了通式为 [Pt(Рpy)(CNR)2]X（HРpy = 2-苯基吡啶；R = iPr、tBu、Cy；X = BF4、OTf、PF6）的环金属化铂（II）配合物，其中含有各种烷基异氰酸酯配体和反离子。通过元素分析、ESI HRMS、红外光谱以及 1H、13C{1H} 和 195Pt{1H} NMR 光谱对这些化合物进行了研究。NMR 光谱。通过 XRD 确定了[Pt(Рpy)(CNiPr)2]BF4 和[Pt(Рpy)(CNtBu)2]BF4 的结构（CIF 文件 CCDC 编号分别为 2325595 和 2325527）。研究了合成化合物在溶液和固体状态下的光物理特性。
