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)(CNtBu)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.
