New di-ferrocenyl-ethynylpyridinyl triphenylphosphine copper halide complexes and related di-ferricenyl electro-crystallized materials.

Three new neutral di-ferrocenyl-ethynylpyridinyl copper complexes, [L2(CuCl)2(PPh3)2] (), [L2(CuBr)2(PPh3)2] (), and [L2(CuI)2(PPh3)2] () were synthesized from the ferrocenyl-ethynylpyridine ligand (L) (), the appropriate copper halide CuX (with X = Cl(-), Br(-), I(-)) and triphenylphosphine. These neutral complexes were fully characterized by spectroscopic methods and by single crystal X-ray crystallography. Cyclic voltammetry in dichloroethane revealed chemically reversible ferrocenyl oxidation signals followed by characteristic "stripping reduction peaks" showing evidence for oxidation-product electro-crystallization.

Solution-processed mesoscopic Bi₂S₃:polymer photoactive layers.

The fabrication of solution-processed nontoxic mesoporous Bi2S3 structures is demonstrated and the suitability of these structures for use in hybrid solar cells investigated. Mesoporous Bi2S3 electrodes are prepared via thermal decomposition of a thin film composed of a bismuth xanthate single source precursor. The resultant Bi2S3 films are made up of regular needles with approximate dimensions of 50×500 nm, as confirmed by scanning electron microscopy (SEM).

New multi-ferrocenyl- and multi-ferricenyl- materials via coordination-driven self-assembly and via charge-driven electro-crystallization.

Three new tetra-ferrocenylethynylpyridinyl copper complexes, L4(CuI)4 (3), L4(CuBr)2 (4), and L4(CuCl)2 (5) have been prepared from the reaction of ferrocenylethynylpyridine (L)(2) with copper halides CuX (with X = I(-), Br(-), Cl(-)).The ligand 2 and the complexes 3-5 have been fully characterized by spectroscopic methods. The structures of 2-4 have been confirmed by single-crystal X-ray crystallography.

The Reaction and Materials Chemistry of [Sn (O) (OSiMe ) ]: Chemical Vapour Deposition of Tin Oxide.

[Sn (O) (OSiMe ) ] and [{Sn(OSiMe ) } ] have been used to deposit SnO thin films by chemical vapour deposition. Films derived from [Sn (O) (OSiMe ) ] comprise uniform cubes and are highly oriented, whereas those deposited from [{Sn(OSiMe ) } ] are made up of a continuous non-oriented layer with oriented cubes on the surface. The structure of a co-crystal, 2 Sn (O) (OSiMe ) ⋅[Sn(OSiMe ) ] ⋅4 THF, shows that [{Sn(OSiMe ) } ], a liquid at room temperature, adopts a μ-OSiMe -bridged dimeric structure.

Thermal decomposition of solution processable metal xanthates on mesoporous titanium dioxide films: a new route to quantum-dot sensitised heterojunctions.

We introduce a straightforward route to the fabrication of metal sulfide semiconductor (e.g. CdS, Sb(2)S(3), Bi(2)S(3)) sensitised TiO(2) films.

The synthesis and reaction chemistry of new amino-functionalised tin(II) alkoxides.

Sn(ii) derivatives of the aminoalcohols (t)Bu(H)NC(Me)(H)CH(2)OH (Htbap, ), (R(1)R(2)NCH(2))(2)C(H)OH (R(1) = R(2) = Me, , Hbdmap; R(1) = (t)Bu, R(2) = H, , Hbtbap), (R(1)R(2)NCH(2))(3)COH (R(1) = R(2) = Me, , Htdmap; R(1) = (t)Bu, R(2) = H, , Httbap) have been synthesised by reaction of the alcohol with Sn[N(SiMe(3))(2)](2). The structures of the ligands , .H(2)O, along with Sn(ttbap)(2) have been determined; the latter is pseudo-trigonal bipyramidal with nitrogen atoms in axial sites and oxygen atoms and a stereochemically-active lone pair in the equatorial positions.

Nanostructured hybrid polymer-inorganic solar cell active layers formed by controllable in situ growth of semiconducting sulfide networks.

Nanostructured composites of inorganic and organic materials are attracting extensive interest for electronic and optoelectronic device applications. In this paper, we introduce a general method for the fabrication of metal sulfide nanoparticle/polymer films employing a low-cost and low temperature route compatible with large-scale device manufacturing. Our approach is based upon the controlled in situ thermal decomposition of a solution processable metal xanthate precursor complex in a semiconducting polymer film.
