Axially Chiral Bis-Cycloplatinated Binaphthalenes and Octahydro-Binaphthalenes for Efficient Circularly Polarized Phosphorescence in Solution-Processed Organic Light-Emitting Diodes

A new series of axially chiral binuclear Pt(II) complexes with bridging ligands of binaphthalenes and octahydro-binaphthalenes and auxiliary ligands of β-diketones were designed and prepared. These complexes, identified by spectral and electrochemical met

First example of the solid-state thermal cyclometalation of ligated benzophenone imine giving novel luminescent platinum(II) species

The (benzophenone imine)platinum(II) compounds trans-[PtCl 2(Ph2C=NH)(RR′SO)] [R, R′ = Me, Me (2); n-Pr, n-Pr (3); (CH2)4 (4); Me, Ph (5); Me, p-MeC 6H4 (6)] were prepared by the reaction of Ph 2C=NH with K[PtCl3(RR′SO)], obtained in situ from K2[PtCl4] and the corresponding sulfoxide, giving 2-6 as well as cis-[PtCl2(Ph2C=NH)2] (1) as a minor product. The complexes were characterized by 1H, 13C, and 195Pt NMR and IR spectroscopy, electrospray ionization mass spectrometry, and C, H, and N elemental analysis. The X-ray crystallography of 1 enables confirmation of the cis configuration of the complex, while in 2 and 4·1/2CHCl3, the imine and sulfoxide ligands are mutually trans. The solid-state structure of 4·1/2CHCl3 consists of two dimeric Pt moieties representing a rather weak Pt...Pt interaction. The dimeric architecture of 4·1/2CHCl3 is enhanced by the hydrogen bonding between imine H atoms and O atoms. The orthometalation of 1 and 2-6 proceeds both in the solid phase and in a toluene suspension, leading to the formation of [PtCl{Ph(C6H4)C=NH}(Ph2C=NH)] (7) and [PtCl{Ph(C6H4)C=NH}(RR′SO)] (8-12), respectively, isolated in nearly quantitative yields. Complexes 8-12 are emissive at room temperature both in solution (λem max ～535 nm) and in the solid state (λem max 560-610 nm), with excited-state lifetimes of ca. 300-600 ns, representing a new family of PtII-based luminescent complexes. Compounds 8 and 10 have been characterized by X-ray analysis, confirming the square-planar coordination geometry of the metal center with the almost planar platinacycles. In 8, the asymmetric unit contains two independent Pt molecules, while in 10, it includes four Pt molecules linked by the intermolecular hydrogen-bonding network between the NH group and Cl atoms.

1H and 13C NMR and CD spectra of platinum complexes with (+)-methyl p-tolyl sulfoxide. Molecular structure and absolute configuration of potassium (-)-trichloro{S-methyl p-tolyl sulfoxide}platinate(II)

The molecular structure and absolute configuration of potassium (-)-trichloro{S-methyl p-tolyl sulfoxide}platinate(II) was determined. Mixed-ligand platinum complexes with (+)-methyl p-tolyl sulfoxide with the general formula Pt[Me(p-Tol)SO]XCl2 (X = CH2=CH2, PBu3, Py, and 4-Pic) were prepared from this complex and studied by 1H and 13C NMR and CD spectroscopy.
