A new class of copper(I) complexes with imine-containing chelators which show potent anticancer activity

Seven novel complexes (C1?C7) were synthesized by the interaction between Cu(I) metal cation, L1, L2, L3, X and PPh3, where L1?L3 are derivatives of ((pyridine-2-ylmethylene)amino)phenol imine ligands and X = Cl?, Br?, I?, NCS?. All the complexes were characterized using infrared, 1H NMR and 31P NMR spectroscopies. The crystal structures of C1?C7 were also determined using single-crystal X-ray diffraction. The organization of the crystal structures and the intermolecular interactions are discussed. The supramolecular assemblies are driven by cooperative pi?pi interactions and hydrogen bonds, followed by CH?pi linkages. The potential anticancer effect of C1?C7 was assessed for human glioblastoma cells using several anticancer experiments, which showed that these complexes have marked anticancer property against U87 cells. It was also found that the minimum and maximum anticancer effects are shown by C3- and C4-treated samples, respectively. Furthermore, theoretical approaches were used to investigate the nature of metal?ligand interactions which suggest a closed-shell and electrostatic character for Cu?N, Cu?P and Cu?X bonds.

A Potential Hybrid Hole-Transport Material Incorporating a Redox-Active Tetrathiafulvalene Derivative with CuSCN

Inorganic CuSCN and organic tetrathiafulvalene derivatives (TTFs) have been exploited as hole-transport materials (HTM) in hybrid perovskite solar cells. To develop new HTM, we herein report two hybrid materials incorporating redox-active TTFs with CuSCN framework (TTFs-CuSCN). Single-crystal analysis showed that compound [Cu2(py-TTF-py)(SCN)2] (1) is three-dimensional (3D) and compound [Cu(py-TTF-py)(SCN)] (2) is two-dimensional (2D) (py-TTF-py = 2,6-bis(4?-pyridyl)tetrathiafulvalene). There are covalent coordination interactions between CuSCN and py-TTF-py and short S···S contacts between the py-TTF-py ligands for both compounds. Besides, C···S contacts exist between py-TTF-py ligands of the neighboring 2D networks in 2, which facilitate the charge transfer and supply efficient multidimensional pathways for carrier migration. As a result, 2 presented better semiconductor performance in comparison with that of 1. The performance of 2 related to the HTMs could be significantly improved by modulating the electronic state of the TTFs-CuSCN framework via oxidative doping. The iodine-doped 2D material (2-I2) gives the most excellent conductivity and carrier mobility, which might be a potential new HTM.

Deep Ultraviolet Copper(I) Thiocyanate (CuSCN) Photodetectors Based on Coplanar Nanogap Electrodes Fabricated via Adhesion Lithography

Adhesion lithography (a-Lith) is a versatile fabrication technique used to produce asymmetric coplanar electrodes separated by a <15 nm nanogap. Here, we use a-Lith to fabricate deep ultraviolet (DUV) photodetectors by combining coplanar asymmetric nanogap electrode architectures (Au/Al) with solution-processable wide-band-gap (3.5-3.9 eV) p-type semiconductor copper(I) thiocyanate (CuSCN). Because of the device's unique architecture, the detectors exhibit high responsivity (?79 A W-1) and photosensitivity (?720) when illuminated with a DUV-range (peak = 280 nm) light-emitting diode at 220 muW cm-2. Interestingly, the photosensitivity of the photodetectors remains fairly high (?7) even at illuminating intensities down to 0.2 muW cm-2. The scalability of the a-Lith process combined with the unique properties of CuSCN paves the way to new forms of inexpensive, yet high-performance, photodetectors that can be manufactured on arbitrary substrate materials including plastic.

Separation of propylene and propane by alkylimidazolium thiocyanate ionic liquids with Cu+ salt

Ionic liquids (ILs) coupled with Ag+ or Cu+ salts to form a new kind of reactive absorbent have been studied to separate light olefin from paraffin recently. In this work, we prepared two halogen-free alkylimidazolium thiocyanate ILs with cheaper cuprous thiocyanate, i.e., [Bmim]SCN-CuSCN and [Emim]SCN-CuSCN (Bmim, 1-butyl-3-methylimidazolium; Emim, 1-ethyl-3-methylimidazolium) and investigated their absorption capability for propylene, propane and mixture of both at 1-7 bar and 298-318 K. The effects of operating parameter including cation nature, temperature, pressure, Cu+ concentration and reuse of absorbent were investigated. Propylene shows a chemical absorption while propane does a physical one, and increasing Cu+ concentration effectively improves the absorption capability for propylene and the selectivity of propylene/propane. [Bmim]SCN-CuSCN has higher absorption capability and selectivity for propylene than [Emim]SCN-CuSCN, e.g., [Bmim]SCN-CuSCN-1.5 M can absorb 0.12 mol of propylene per liter while 0.012 mol of propane per liter at 1 bar and 298 K, with a selectivity of 10, which is comparable to some other ILs-Ag+ salts and better than pure ILs. Such absorbents can be regenerated through temperature and pressure swing without remarkable activity loss. This work shows that alkylimidazolium thiocyanate ILs with Cu+ salts are promising reactive absorbents to separate propylene from propane.

We’ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of 1111-67-7, and how the biochemistry of the body works.Recommanded Product: Cuprous thiocyanate

In situ imaging Raman spectroscopy of electrochemically deposited CuSCN

Imaging Raman spectroscopy is explored as a new tool for in situ studies of electrochemical systems. The technique provides a spatially resolved view of molecular species present along a focused laser line. The capabilities of our system are demonstrated using an electrodeposited thin film of CuSCN plated on a cylindrical platinum electrode. It is shown that line-imaging Raman spectroscopy is able to measure the properties of the thin film deposit while simultaneously monitoring the concentration of solution species within ? 1 mm of the surface. The Raman image presented here has a spatial resolution of ?6 mum and a spectral resolution of 24 cm-1, though neither constitutes resolution limits of the instrument.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Reference of 1111-67-7, you can also check out more blogs aboutReference of 1111-67-7

Synthesis, spectroscopic and structural characterization of some novel adducts of copper(II) salts with unidentate nitrogen bases

Syntheses, spectroscopic characterization and single crystal X-ray studies are reported for a number of complexes of copper(II) salts with simple monodentate nitrogen bases. The 1:4 adduct of copper(II) sulfate with 3,5-dimethylpyridine (m2py) CuSO4·4m2py, takes the form [(O3SO)Cu(m2py)4], the Cu-O vector of the square-pyramidal coordination environment being disposed on the 4-axis in tetragonal space group P4/n. The complex CuCO3· Cu(NCS)2·4py is a linear polymer, taking the form ?O·Cu(py)2·O·C{O·Cu(py) 2(NCS)2}·O·Cu(py)2? (etc.), all atoms lying in the mirror plane of space group Pnma, excepting the pair of ‘py’ (pyridine) ligands disposed to either side. In Cu(OH)I·3/ 4I2·2py·1/2MeCN ? [{(py)2Cu(OH)} 4](I3)3I·2MeCN a novel cubanoid tetranuclear cation is found (2-symmetry). The EPR spectra of the above compounds show a trend in the anisotropy of the g-values that correlates well with the crystal structures. Obtained only in small quantities but supported by single crystal X-ray studies are the adduct of Cu(OH)Cl with pyrrolidine (pyrr), Cu(OH)Cl:pyrr (1:3), which takes the centrosymmetric binuclear form [(pyrr)3Cu(mu-OH)2Cu(pyrr)3]Cl2, the copper atom being disposed in a distorted trigonal bipyramidal array, and the adduct 3CuCl2·CuO·4quin, [Cu4Cl 6O(quin)4]Cl2, which contains the familiar Cu4Cl6O core with monodentate quinuclidine (quin) attached to the copper atoms; this compound crystallizes in the cubic space group 4?3m.
