Stepwise addition of CuNCS onto [Et4N][Tp*WS3]: Design, syntheses, structures and third-order nonlinear optical properties

Stepwise reactions of [Et4N][Tp*WS3] (1) (Tp* = hydridotris(3,5-dimethylpyrazol-1-yl)borate) with 1-4 equiv. of CuNCS (and Et4NBr in the case of three equiv. of CuNCS) afforded the [1 + 1] to [1 + 4] addition products [Et4N][Tp*WS(mu-S) 2(CuNCS)]·0.5CH2Cl2 (2·0.5CH 2Cl2), [Et4N][Tp*W(mu3-S) (mu-S)2(CuNCS)2]·ClCH2CH 2Cl (3·ClCH2CH2Cl), [Et 4N]2[Tp*W(mu3-S)3(CuNCS) 3(mu3-Br)]·1.5aniline (4·1.5aniline), and {[Et4N][Tp*W(mu3-S)3(Cu-mu-SCN) 3(Cu-mu3-NCS)]}n (5). Compounds 2-5 were characterized by elemental analysis, IR spectra, UV-vis spectra, 1H NMR, and single-crystal X-ray crystallography. The cluster anion of 2 contains a [WS2Cu] core formed by addition of one CuNCS group onto the [Tp*WS3] species. The cluster anion of 3 has a butterfly-shaped [WS3Cu2] core constructed by addition of two CuNCS groups onto the [Tp*WS3] species. The cluster dianion of 4 consists of a cubane-like [Tp*WS3Cu3(mu3-Br)] core assembled by addition of three CuNCS groups onto the [Tp*WS 3] species followed by filling a mu3-Br into the void of the incomplete cubane-like [Tp*WS3(CuNCS)3] fragment. 5 has a 2D cluster-supported layer network in which each [Tp*WS3Cu3] core acting as a pyramidal 3-connecting node interconnects with the [Cu(NCS)4] units through thiocyanate bridges. In addition, the third-order nonlinear optical (NLO) performances of 2-5 in DMF were also investigated by Z-scan techniques.

A solar cell sensitized with three different dyes

Construction of a semiconductor – dye heterostructure of the configuration n-TiO2/D1/p-CuSCN/D2/p-CuSCN/D 3/p-CuSCN. (n-TiO2 is the nanocrystalline TiO2 film deposited on conducting glass, p-CuSCN = ultra-thin (?2 nm) layers of Cu(I) thiocyanate, p-CuSCN = thick layer of p-CuSCN, D 1 = Fast Green, D2 = Rhodamine 6G and D3 = Acridine Yellow) is described. It is found that this heterojunction generates photovoltaic response to light absorption by all the three dyes. The mechanism involved is suggested to be transfer of electrons to n-TiO2 and holes to p-CuSCN via tunneling. This technique could be a strategy to broaden the spectral response and enhance the efficiency of dye-sensitized solar cells.

Front dielectric and back plasmonic wire grating for efficient light trapping in perovskite solar cells

Thin film perovskite solar cells (PSCs) based on (CH3NH3PbI3) have been emerged as good alternatives to conventional silicon solar cells due to their low cost, low fabrication temperature, high carrier collection efficiency, and high-power conversion efficiency (PCE). However, the small thickness of thin film solar cells limits light absorption compared to thick solar cells. In this work, we proposed a theoretical design for enhancing light absorption to achieve maximum theoretical photocurrent using front dielectric and back plasmonic wire grating. Using finite element method (FEM) three-dimensional optical model, the optimum size and periodicity of the studied wire grating nanostructures were identified. Additionally, the electrical model revealed a satisfactory enhancement in PCE over that of the planar structure counterpart. The simulation results showed an average enhancement of 22.4% in total generation rate for the entire simulated wavelength, and more than 85% enhancement in narrow-band wavelength compared to the planar structure counterpart.

Tubulin binding ligands and corresponding prodrug constructs

A diverse set of tubulin binding ligands have been discovered which are structurally characterized, in a general sense, by a semi-rigid molecular framework capable of maintaining aryl-aryl, pseudo pi stacking distances appropriate for molecular recognition of tubulin. In phenolic or amino form, these ligands may be further functionalized to prepare phosphate esters, phosphate salts, and phosphoramidates capable of demonstrating selective targeting and destruction of tumor cell vasculature.

Extended supramolecular structures derived from metal pseudohalides and 4,4?-bipyridinium derivative: Synthesis, structures and optical properties

Four novel extended supramolecular structures based on pseudohalides (SCN) and the flexible cationic ligand 1,4-bis(4,4?-bipyridinium)butane ditetrafluoroborate (bbpyb), namely [bbpyb][Hg(SCN)4] (1), [Cu2(bbpyb)(SCN)4]n (2), [Ag2(bbpyb)(SCN)4]n (3) and [Cu6(bbpyb)(SCN)8]n (4) have been solvothermally synthesized and characterized by IR spectroscopy, thermal gravimetric analysis(TGA), PXRD, UV-Vis diffuse reflectance spectra and single-crystal X-ray diffraction in the solid state. Compound 1 is a 0D supramolecular structure consisted of one linear cationic ligand bbpyb2+ and inorganic mononuclear anion [Hg(SCN)4]2-. Compounds 2 and 3 exhibit infinite two-dimensional anionic architecture, which represent the same (6,3) topology. In compound 4, the cationic ligand bbpyb2+ bridge [Cu6(SCN)8] cluster unit to generate a 3D coordination framework. The structural diversities show that the pseudohalides (SCN) and cationic ligand should very likely be excellent candidates to construct higher dimensional extend supramolecular architectures. In addition, the optical band gap and photocatalytic properties of compounds 1-4 were also investigated.
