First microwave-assisted synthesis of an electron-rich phosphane and its coordination chemistry with platinum(II) and palladium(II)

The P–O ligand 3-(di(2-methoxyphenyl)phosphanyl)propionic acid (HL) was synthesized by a microwave-assisted reaction of a secondary phosphane. The coordination of HL to PtII yielded the neutral mononuclear complex trans-[PtCl(κ2-P,O-L)(κ-P-HL)] (1), while the reaction of PdClMe(η4-COD) (COD = 1,4-cyclooctadiene) with HL in the presence of NEt3 gave the anionic PdII compound of the formula (HNEt3)[PdClMe(κ2-P,O-L)] (2). Upon crystallization of the latter compound the neutral chloride-bridged dimetallic compound cis-[Pd(μ-Cl)Me(HL)]2 (3) was obtained. HL, 1 and 3·CH2Cl2 have been characterized by single crystal X-ray structure analyses

Luminescent Dinuclear Cu(I) Complexes Containing Rigid Tetraphosphine Ligands

The synthesis and the photophysics of three dinuclear copper­(I) complexes containing bis­(bidentate)­phosphine ligands are described. The steric constraint imposed by tetrakis­(di­(2-methoxyphenyl)­phosphanyl)­cyclobutane) (o-MeO-dppcb) in combination with 2,9-dimethyl-1,10-phenanthroline in one of the complexes leads to interesting photophysical properties. The compound shows an intense emission at room temperature in deoxygenated acetonitrile solution (Φ = 49%) and a long excited-state lifetime (13.8 μs). Interestingly, at low temperature, 77 K, the emission maximum shifts to lower energy, and the excited-state lifetime increases. This observation leads to the conclusion that a mixing between the excited triplet and singlet states is possible and that the degree of mixing and population of state strongly depends on temperature, as the energy difference is quite small. The electroluminescent properties of this compound were therefore tested in light-emitting electrochemical cells (LEECs), proving that the bright emission can also be obtained by electrically driven population of the singlet state
