Luminescent heteroleptic Cu(I) complexes based on asymmetrical iminephosphine ligands exhibit improved electrochemical and photochemical stability as compared to the analogous complexes based on traditional diimine or diphosphine ligands.

Using the HETPHEN approach, five new heteroleptic copper(I) complexes composed of a push-pull 4,4'-styryl-6,6'-dimethyl-2,2'-bipyridine ligand and a bulky bis[(2-diphenylphosphino)phenyl]-ether (DPEphos) or a bis2,9-mesityl phenanthroline (Mes2Phen) were prepared and characterized by electronic absorption spectroscopy, electrochemistry, and TD-DFT calculations. These complexes exhibit very inte...

The synthesis and characterization of a series of dibenzhydryl-based α-diimine Ni(II) complexes bearing a range of electron-donating or -withdrawing groups are described. Polymerization with ethylene is investigated in detail, involving the activator effect, influence of polymerization conditions on catalyst activity, thermal stability, polymer molecular weight and melting point. All of these N...

A series of α-diimine Ni(II) complexes containing bulky phenyl groups, [ArN = C(Naphth)C = NAr]NiBr2 (Naphth: 1,8-naphthdiyl, Ar = 2,6-Me2-4-PhC6H2 (C1); Ar = 2,4-Me2-6-PhC6H2 (C2); Ar = 2-Me-4,6-Ph2C6H2 (C3); Ar = 4-Me-2,6-Ph2C6H2 (C4); Ar = 4-Me-2-PhC6H3 (C5); Ar = 2,4,6-Ph3C6H2 (C6)), were synthesized and characterized. Upon activation with either diethylaluminum chloride (Et2AlCl) or modifi...

Platinum diimine complexes can covalently be grafted onto oxide-free, hydrogen-terminated silicon(111) surfaces into clean and high-quality monolayers. The so modified offer great prospects as photocathodes for solar-driven electrocatalysis.

We report the formation of dinuclear complexes from, and photochemical oxidation of, (CH3)3-Pt(IV)(N^N) (N^N = 1,2-diimine derivatives) thiophenolate ligands to analogous sulfinates (CH3)3Pt(N^N)(SO2Ph) structural, spectroscopic, theoretical studies latter revealing tunable photophysics depending upon ligands. Electron-rich thiolate conjugated 1,2-diimines encourage thiolate-bridged complexes; ...

Diimine and diamine ligands that are unable to coordinate to a single metal favour the formation of unusual, high-nuclearity Zn chlorometallate and palladium chloride complexes.

Platinum diimine bis(alkynyl), bis(thiolate) or bis(alkoxolate) complexes (diimine)Pt(XR)2 (XR=C CR, OR, SR) constitute a prominent class of photosensitizers with numerous applications in the fields of photocatalysis and light to (chemical) energy conversion; e.g., photocatalysed hydrogen production. The photoreactive state is usually accessed by excitation into the (RX)2Pt-diimine charge-trans...
