Two novel nanoporous supramolecular architectures based on copper(I) coordination polymers with uniform (8, 3) and (8210) nets: In situ formation of tetrazolate ligands

The hydro/solvothermal reactions of Cu(I)/Cu(II) salt, NaN3, and acetonitrile in water or methanol yield two noninterpenetrated supramolecular networks containing 1D hexagonal and square nanochannels, {[Cu(Mtta)]¡¤0.17H2O}n (1) and its pseudopolymorph [Cu(Mtta)]n (2) (Mtta = 5-methyl tetrazolate), involving ligand insitu formation by cycloaddition of nitriles and azides. The copper-(I) centers in both complexes are all bridged by Mtta ligands, forming the different shapes of the cavity. 1 exhibits an unprecedented uniform (8, 3) topological metal network, whereas 2 is a 3-connected (8210) metal net.

Wavelength dependent photochemical charge transfer at the Cu2O-BiVO4 particle interface-evidence for tandem excitation

The understanding of the photochemical charge transfer properties of powdered semiconductors is of relevance to artificial photosynthesis and the production of solar fuels. Here we use surface photovoltage spectroscopy to probe photoelectrochemical charge transfer between bismuth vanadate (BiVO4) and cuprous oxide (Cu2O) particles as a function of wavelength and film thickness. Optimized conditions produce a -2.10 V photovoltage under 2.5 eV (0.1 mW cm-2) illumination, which suggests the possibility of a water splitting system based on a BiVO4-Cu2O direct contact particle tandem.

Homonuclear and heteronuclear complexes of calix[4]-bis-monothiacrown-5 with oligomer and polymer structures

Homo- and heteronuclear complexes (1-7) of calix[4]-bis-monothiacrown-5 (L) with mercury(II), cadmium(II), copper(I), and potassium(I) salts adopting dimer, tetramer, one-dimensional (1D), and two-dimensional (2D) polymer structures with different coordination modes and connectivity patterns were prepared and structurally characterized. Reactions of L with mercury(II) iodide and mercury(II) thiocyanate afforded a dimer complex [Hg4(L)2I8]¡¤CH2Cl2 (1) and a 1D coordination polymer {[Hg2(L)(SCN)4]¡¤CH2Cl2}n (2), respectively, in which the exocyclic dimercury(II) complex units of L are doubly linked by the anions. Reactions of L with cadmium(II) iodide in the absence and the presence of mercury(II) iodide gave isostructural 1D coordination polymers [Cd2(L)I4]n (3) and {[Cd2(L)I4][CdHg(L)I4]}n (4), respectively. In the isostructure of 3 and 4, the ligands are alternately linked by the exocyclic M-I2-M squares via monocadmium(II)-mediated and dicadmium(II)-mediated modes, respectively. Reaction of L with copper(II) thiocyanate in the presence of potassium(I) thiocyanate afforded a discrete complex {[(K2L)4Cu6(SCN)10][K2L]2[Cu(SCN)3]3¡¤2CH2Cl2¡¤CH3CN} (5) consisting of three separated parts: dipotassium(I) tetramer part linked with a oligomer copper(I) thiocyanate backbone, dipotassium(I) monomer part, and trithiocyanato copper(I) complex part.

One pot reaction of L with a mixture of iodide salts of potassium(I), mercury(II), and cadmium(II) gave a binary mixed product of a discrete complex [(K2L)2(Cd3I8)][Cd4I10] (7) and a heteronuclear 2D network (8) which can be manually separated because of the colorless platy and orange-yellow block shapes of the crystals, respectively. In 7, the endocyclic dipotassium(I) complex of L is linked by Cd3I8 clusters. (Chemical Equation Presented).

Compositionally tunable Cu2ZnSn(S1-xSe x)4 nanocrystals: Probing the effect of Se-inclusion in mixed chalcogenide thin films

Nanocrystals of multicomponent chalcogenides, such as Cu 2ZnSnS4 (CZTS), are potential building blocks for low-cost thin-film photovoltaics (PVs). CZTS PV devices with modest efficiencies have been realized through postdeposition annealing at high temperatures in Se vapor. However, little is known about the precise role of Se in the CZTS system. We report the direct solution-phase synthesis and characterization of Cu 2ZnSn(S1-xSex)4 nanocrystals (0 ? x ? 1) with the aim of probing the role of Se incorporation into CZTS. Our results indicate that increasing the amount of Se increases the lattice parameters, slightly decreases the band gap, and most importantly increases the electrical conductivity of the nanocrystals without a need for annealing.

Novel 2D material from AMQS-based defect engineering for efficient and stable organic solar cells

In this work, soluble two-dimensional (2D) material of antimonene quantum sheets (AMQSs) is used to form a bilayer hole extraction layer (HEL) with CuSCN. It proves that the application of AMQSs helps to passivate surface defects of CuSCN, resulting in diminished recombination loss and depressed exciton quenching effect, and thereby achieving improved photovoltaic performance. In OPVs based on poly[4,8-bis(5-(2-ethylhexyl)thiophen-2-yl)benzo[1,2-b;4,5-b?]dithiophene-2,6-diyl-alt-(4-(2-ethylhexyl)-3-fluorothieno[3,4-b]thiophene-)-2-carboxylate-2-6-diyl)]: [6,6]-phenyl C71-butyric acid methyl ester (PTB7-Th:PC71BM), over 12% enhancement of power conversion efficiency (PCE) is observed compared to that of the reference cell fabricated with pure CuSCN as an HEL. The advantage of the bilayer CuSCN/AMQS HEL is also confirmed in non-fullerene systems of PBDB-T-2F:IT-4F and PTB7-Th:ITIC. In a cell based on PBDB-T-2F:IT-4F, a PCE of 10.14% was obtained after application of AMQSs, which improved by about 10% compared to that of the reference cell using pure CuSCN as an HEL. Furthermore, cells based on CuSCN and CuSCN/AMQS HEL exhibit superior air stability. The use of a bilayer CuSCN/AMQS HEL provides a promising approach to obtain efficient and stable organic solar cells.

Construction of copper-based coordination polymers with 1D chain, 2D plane and wavy networks: Syntheses, structures, thermal behavior and photoluminescence properties

Three Cu-based coordination polymers (CPs), including [Cu II(N- eta 1-NCS) 2(O- eta 1-DMF) 2(mu 2-3,3′-bptz)] n (1), [Cu I(1,3- mu 2-NCS)(mu 2-3,3′-bptz)] n (2) and [(Cu I(1,3- mu 2- NCS))(mu 2-4,4′-bptz)] n (3) (DMF = N, N-dimethyl formamide, 3,3′-bptz = 3,6-bis(3-pyridyl)tetrazine and 4,4′-bptz = 3,6-bis(4-pyridyl)tetrazine) have been successfully constructed by solution diffusion reactions by using Cu(NO 3) 2.3H 2O or CuNCS and KNCS with 3,3′-bptz / 4,4′-bptz ligands, respectively. The resulting crystalline materials have been characterized by the single-crystal X-ray diffraction analyses, elemental analyses, FT-IR spectra, thermogravimetric analyses and powder X-ray diffraction (PXRD). Single crystal X-ray analyses revealed that CP 1 is organized in one-dimensional (1D) chain in which the Cu(II) ions are coordinated by eta 1-NCS – anions and eta 1-DMF molecules, and linked by mu 2-3,3′-bptz bridging ligands. CPs 2 and 3 are structural isomers. CP 2 exhibits two-dimensional (2D) (4,4)-plane-like network in which Cu(I) ions are linked by mu 2-NCS – and mu 2-3,3′-bptz ligands. In CP 3, Cu(I) ions are connected by mu 2-NCS – and mu 2-4,4′-bptz ligands to form 2D saw-tooth wavy network. In addition, the photoluminescence properties of CPs 1-3 were also investigated in the solid state at room temperature.
