Semiconductor nanostructures in an alumina template matrix: Micro- versus macro-scale photoelectrochemical behavior

We show herein that the photoelectrochemical behavior of a given semiconductor nanodot (p-CuSCN or n-TiO2) in an alumina template matrix, is remarkably different than that of its macro-sized counterpart. Three separate examples of this distinct difference in behavior are presented. It is shown how the photoresponse (e.g. photocurrent) may be amplified (from a low level typical of the signal emanating from a ?10-11 cm2 region corresponding to a semiconductor nanodot) by using a large number of electrically inter-connected Au nanowires to support the overlying semiconductor nanodots. The anomalous photoresponse of p-CuSCN nanodots in the template matrix was also numerically simulated by a simple parallel equivalent circuit consisting of a semiconductor and a photocapacitor. Possible practical application scenarios are finally presented for these nanostructures.

Process for preparing 3,5-difluoroaniline

The invention provides a novel process for producing a 3,5-difluoroaniline compound by reacting a 2-halo-4,6-difluoroaniline with a diazotizing agent in the presence of a reducing agent to form a diazonium salt. Build-up of potentially dangerous diazonium salt is avoided by reducing the diazonium salt with the reducing agent, to form a 1-halo-3,5-difluorobenzene, contemporaneously with the diazotization reaction. The 1-halo-3,5-difluorobenzene is then aminated.

ALLYLIC VERSUS VINILIC OXIDATION OF CYCLOHEXENE PROMOTED BY TRANSITION METAL beta-DIKETONATES

We report the cyclohexene oxidation by molecular oxygen in the presence of several metal beta-diketonates. The catalytic conditions used showed an allylic/vinilic oxidation (ao/av) ratio equal 1.5. The complexes M(l)n were used with the metal ions Co(III), Ni(II), Pd(II), Cu(II), chelated with acetylacetone (AcAc), benzoylacetone (BeAc) and dibenzoylacetone (BeBe) as ligands. The oxidation selectivity of the studied system suggests a different allylic/vinylic pathway compared with that observed inprevious reports.

Single-crystal X-ray structural characterizations of MX:dpam (1:1) (‘dpam’ = Ph2AsCH2AsPh2) are reported for MX = AgCl, Br; CuI, CN/Cl (all isomorphous) and AgI, AgSCN, CuSCN arrays, all being of the novel form [(mu-X){M(mu-X)(As-dpam-As?)2M?}] ?, essentially the familiar M(E-dpem-E?) 2M? binuclear array with both ‘bridging’ and (linking) ‘terminal’ (pseudo-)halides involved in the polymer. A different arrangement of bridging and linking entities is found with AgX:dpae (1:1) 2(?|?), X = Br, NCO, ‘dpae’ = Ph2As(CH 2)2AsPh2, now comprising [M(mu-X) 2(As-dpae-As)M] kernels linked by As-dpae-As?, while in the thiocyanate analogue Ag(NCSSCN)Ag units are linked by the dpae ligands into a two-dimensional web. Synthetic procedures for all adducts have been reported. All compounds have been characterized both in solution (1H, 13C, 31P NMR, ESI MS) and in the solid state (IR).

The coordination chemistry of mono and bis(di-2-pyridylamine)copper(II) complexes: Preparation, characterization and crystal structures of [Cu(L)(NO2)2], [Cu(L)(H2O)2(SO4)], [Cu(L)2(NCS)](SCN)¡¤0.5DMSO and [Cu(L)2(SCN)2]

The crystal structures of two mono(dpyam)copper(II) complexes, [Cu(dpyam)(NO2)2] (1) and [Cu(dpyam)(H2O)2(SO4)] (2) and two dithiocyanate compounds containing bis(dpyam)copper(II) units, [Cu(dpyam)2(NCS)](SCN)¡¤0.5DMSO (3) and [Cu(d- pyam)2(SCN)2] (4) have been determined by X-ray crystallography. The second orthorhombic form of the monomeric Cu(II) complex 1 was obtained by the reaction of di-2-pyridylamine (dpyam) with CuCl and NaNO2 in water-methanol solution. Each copper(II) ion in 1 exhibits a tetrahedrally-distorted square base of the CuN2O2 chromophore, with off-the-z-axis coordinated nitrito groups weakly bound in approximately axial positions. Complex 2 is an example of a polymeric copper(II) derivative containing the bidentate bridging sulfate ligand in the long-bonded axial positions. Each copper(II) ion in 2 shows an elongated tetragonal octahedral stereochemistry. The CuN4N? chromophore of 3 involves a square-based pyramidal structure, slightly distorted towards a trigonal bipyramidal stereochemistry, tau = 0.13. One of the SCN- anions is bonded to the copper(II) ion via the N atom in the axial position of the square pyramid. Complex 4 is centrosymmetric and octahedrally elongated, with the SCN- anions coordinating in axial positions via the S atom. The structures of complexes 1-4 and their ESR and electronic reflectance spectra are compared with those of related complexes.

Tuning chemistry of CuSCN to enhance the performance of TiO 2/N719/CuSCN all-solid-state dye-sensitized solar cell

CuSCN with enhanced p-type conductivity was prepared by replacing some of the cuprous sites by triethylamine coordinated Cu(i) with concomitant (SCN) 2 doping to introduce more holes. A compound Cu5[(C 2H5)3N]3(SCN)11 was isolated and well characterized. A 41% enhancement of energy conversion efficiency of the TiO2/N719/modified CuSCN cell from the best reported value and more than a factor of ten from bare CuSCN was achieved.

The structural definition of adducts of stoichiometry MX:dppx (1:1) M = CuI, AgI, X = simple anion, dppx=Ph2P(CH 2)xPPh2, x = 3-6

Single crystal X-ray structural characterizations are recorded for a wide range of adducts of the form MX:dppx (1:1)(n), M = silver(I) (predominantly), copper(I), X = simple (pseudo-) halide or oxy-anion (the latter spanning, where accessible, perchlorate, nitrate, carboxylate – a range of increasing basicity), dppx=bis(diphenylphosphino)alkane, Ph2P(CH 2)xPPh2, x = 3-6. Adducts are defined of two binuclear forms: (i) [LM(mu-X)2L], with each ligand chelating a single metal atom, and (ii) [M(mu-X)2(mu-(P-L-P?)) 2M?] where both ligands L and halides bridge the two metal atoms; a few adducts are defined as polymers, the ligands connecting M(mu-X)2M? kernels, this motif persisting in all forms. Synthetic procedures for all adducts have been reported. All compounds have been characterized both in solution (1H, 13C, 31P NMR, ESI MS) and in the solid state (IR).

Syntheses, crystal structures and nonlinear optical properties of heteronuclear clusters [MS4Cu4(SCN)2(NC5H5) 6] (M=W, Mo)

The title compounds [MS4Cu4(SCN)2(NC5H5) 6] (M=W (1); M=Mo (2); NC5H5=pyridine) were obtained by the reaction of (NH4)2MS4, CuSCN, KSCN and pyridine. The X-ray analyses of 1 and 2 show that four edges of the tetrahedral MS42- core are coordinated by four copper atoms, giving an MS4Cu4 aggregate of approximate D2h symmetry. The nonlinear optical properties of 1 and 2 were investigated by a Z-scan technique with 7 ns laser pulses of 532 nm. The third-order nonlinearities were determined with alpha2=4.3¡Á10-5 and 4.1¡Á10-5 cm W-1 M-1; and n2=-4.3¡Á10-10 and -4.1¡Á10-10 cm2 W-1 M-1, respectively, for compounds 1 and 2.
