The side chain template effect in viologen on the formation of polypseudorotaxane architecture: Six novel metal coordination polymers and their properties

The reaction of CuSCN (or CuCl2) in the presence of excess KSCN directed by viologen-based linear templates in a dimethyl formamide-methanol system affords six coordination polymers, {(MV)[Cu2(SCN) 4]}n (1, MV2+ = 1,1?-dimethyl-4,4?- bipyridinium), {(PrV)[Cu2(SCN)4]}n (2, PrV 2+ = 1,1?-dipropyl-4,4?-bipyridinium), {(iPV)[Cu 2(SCN)4]}n (3, iPV2+ = 1,1?-diisopropyl-4,4?-bipyridinium), [(1-iBV)Cu2(SCN) 3]n (4, 1-iBV2+ = 1-isobutyl-4,4?- bipyridinium), {(iBV)[Cu2(SCN)4]}n (5, iBV 2+ = 1,1?-diisobutyl-4,4?-bipyridinium), and {(PtV)[Cu2(SCN)4]}n (6, PtV2+ = 1,1?-dipentyl-4,4?-bipyridinium). The [Cu2(SCN) 4]n anion in compounds 1, 3 and 5 adopts an infinite two-dimensional polypseudorotaxane architecture and proved effectively that the stoppers at the end can enhance the polyrotaxane formation in the crystalline state, whereas the anion moieties in compounds 2 and 6 exhibit one-dimensional linear architectures, suggesting dethreading from envelopes once solidifying from solution phase. Compound 4 was found to be a two-dimensional coordination polymer with the organic ligand carrying a single charge. The side chain template effect of substituted group, UV-Vis diffuse reflectance spectra in the solid state and TGA properties of the six complexes are investigated.

Highly Stable and Efficient Perovskite Solar Cells with 22.0% Efficiency Based on Inorganic?Organic Dopant-Free Double Hole Transporting Layers

Most of the high performance in perovskite solar cells (PSCs) have only been achieved with two organic hole transporting materials: 2,2?,7,7?-tetrakis(N,N-di-p-methoxyphenylamine)-9,9-spirobifluorene (Spiro-OMeTAD) and poly(triarylamine) (PTAA), but their high cost and low stability caused by the hygroscopic dopant greatly hinder the commercialization of PSCs. One effective alternative to address this problem is to utilize inexpensive inorganic hole transporting layer (i-HTL), but obtaining high efficiency via i-HTLs has remained a challenge. Herein, a well-designed inorganic?organic double HTL is constructed by introducing an ultrathin polymer layer dithiophene-benzene (DTB) between CuSCN and Au contact. This strategy not only enhances the hole extraction efficiency through the formation of cascaded energy levels, but also prevents the degradation of CuSCN caused by the reaction between CuSCN and Au electrode. Furthermore, the CuSCN layer also promotes the formation of a pinhole-free and compact DTB over layer in the CuSCN/DTB structure. Consequently, the PSCs fabricated with this CuSCN/DTB layer achieves the power conversion efficiency of 22.0% (certified: 21.7%), which is among the top efficiencies for PSCs based on dopant-free HTLs. Moreover, the fabricated PSCs exhibit high light stability under more than 1000 h of light illumination and excellent environmental stability at high temperature (85 C) or high relative humidity (>60% RH).

Enhancement of efficiency and stability of CH3NH3GeI3 solar cells with CuSbS2

In this present work we report a numerical modeling of methylammonium germanium tri-iodide-based perovskite solar cells using 1D-SCAPS simulation program. To enhance the device performances, improvement of the device structure and both electron transport and hole transport materials is the effective way. Accordingly, this study is mainly focused on exploring of potentially high-stable hole transport materials (HTMs). Diverse HTMs were suggested, including organic and inorganic materials, and investigated to enhance the reproducibility and stability of CH3NH3GeI3-based perovskite solar cells. Among the proposed materials, copper antimony sulfide (CuSbS2) is the most suitable HTM. Hence, employing CuSbS2 as HTM in perovskite solar cell, the power conversion efficiency is significantly enhanced, and its value achieving 23.58%. Therefore, the obtained results make CuSbS2 an excellent candidate for improving the performance of Ge-perovskite solar cells.

Design, synthesis, and SAR of cis-1,2-diaminocyclohexane derivatives as potent factor Xa inhibitors. Part I: Exploration of 5-6 fused rings as alternative S1 moieties

A series of cis-1,2-diaminocyclohexane derivatives were synthesized with the aim of optimizing previously disclosed factor Xa (fXa) inhibitors. The exploration of 5-6 fused rings as alternative S1 moieties resulted in two compounds which demonstrated improved solubility and reduced food effect compared to the clinical candidate, compound A. Herein, we describe the synthesis and structure-activity relationship (SAR), together with the physicochemical properties and pharmacokinetic (PK) profiles of some prospective compounds.

Magnetic, Spectral and Thermal Studies on Some Mixed Ligand Complexes of Copper(II) and Nickel(II)

Several mixed ligand complexes of copper(II) and nickel(II) having the compositions and , where aaH is acetylacetone, tcaH is trichloroacetic acid; L is gamma-picoline, imidazole, 2-picoline-N-oxide or thiourea and M is Cu(II) or Ni(II), have been isolated and characterised on the basis of their analyses, molar conductance, magnetic susceptibility, infrared, electronic spectral data and thermogravimetric measurements.The infrared spectra reveal the presence of uninegative bidentate acetyl acetonate and trichloroacetate groups in all these complexes.As the temperature increases, the mixed ligand complexes start decomposing with the loss of neutral donor ligand, followed by trichloroacetate ion and acetylacetonate ion in definite steps and ultimately forming MO at 600-675 deg .Square planar, tetrahedral, distorted octahedral and octahedral structures have been proposed for the complexes, , , and , respectively.

Practical Reagents and Methods for Nucleophilic and Electrophilic Phosphorothiolations

New late-stage phosphorothiolation methods are disclosed that allow the efficient transfer of SP(O)(OR)2 groups to diversely functionalized substrates using nucleophilic and electrophilic reagents. The nucleophilic reagent, tetramethylammonium O,O-dimethyl phosphorothioate, was synthesized in near-quantitative yield from Me3SiP(O)(OMe)2, elemental sulfur and Me4NF. Its umpolung with N-bromophthalimide provided the electrophilic reagent, O,O-dimethyl-S-(N-phthalimido)phosphorothioate. Complementary methods based on these reagents enable the phosphorothiolation of diversely functionalized alkyl halides, arenediazonium salts, arylboronic acids and electron-rich arenes in good yields under mild conditions.
