Synthesis, structure, spectroscopy, and magnetism of two new dinuclear carbonato-bridged Cu(II) complexes

Two new dinuclear mu-CO32- Cu(II) complexes with different coordination modes for the carbonato bridge have been obtained by fixation of atmospheric CO2 and also directly prepared from the carbonate salt. The compounds comprise: [Cu2(mu-CO3)(dpyam)4](ClO4) 2(H2O)4 (1), and [Cu2(mu-CO3)2(dpyam)2](H 2O) (2), (in which dpyam = di-2-pyridylamine). For 1, the carbonate ligand acts as a bridge between two Cu(II) centres showing an anti-anti (mu-eta1-eta1-CO32-) coordination mode with a distorted square-based pyramidal geometry for each Cu(II) environment. Complex 2 involves the di-mu-CO32- bridge with a novel tridentate mu-eta1-eta2-CO32- coordination mode. The geometry around each copper atom is distorted square-based pyramidal. Susceptibility measurements for both complexes show a weak to moderately strong antiferromagnetic coupling with J values of -90.4 and -9.9 cm-1 for 1 and 2, respectively. The tridentate co-ordination mode of the carbonate bridge in 2 has not previously been reported for dinuclear Cu(II) complexes. Also its magnetic behaviour and superexchange pathway are discussed.

Structural versatility and electronic structures of copper(i) thiocyanate (CuSCN)-ligand complexes

Copper(i) thiocyanate (CuSCN) is a promising semiconductor with an expansive range of applications already demonstrated. Belonging to the group of coordination polymers, its structure can be easily modified, for example via ligand (L) coordination. In this work, we have analyzed in detail the crystal structures of 26 CuSCN-L complexes that exhibit diverse structures changing from the 3D networks of the parent CuSCN to 2D sheet, 1D ladder, 1D zigzag chain, 1D helical chain, and a 0D monomer as well as intermediate bridged structures. We outline herein the basic structural design principles based on four factors: (1) Cu(i) geometry, (2) CuSCN?:?L ratio, (3) steric effects, and (4) supramolecular interactions. In addition, we employ density functional theory to study the electronic structures of these 26 complexes and find that the opto/electronic properties vary over a wide range, e.g., widened or reduced fundamental band gaps, restricted hole transport due to Cu-SCN network disruption, and the possibility of electron transport through the ligand states. We also observe a correlation between the electronic properties and the dimensionality of the Cu-SCN network. Lowering the dimensionality of the 3D structure to 2D, 1D, and 0D by increasing the number of coordinating ligands, the dispersion and the width of the top valence bands decrease whereas the energy difference between the Cu and SCN states expands. Aliphatic ligands in most cases do not generate electronic states in the band gaps whereas aromatic ligands give rise to states between the Cu and SCN states that lead to optical absorption and emission in the visible range. This study provides guidelines for developing coordination polymer semiconductors based on the Cu-SCN network. The 2D structure is identified as a promising platform for designing new CuSCN-based materials as it retains the carrier transport properties while allowing for properties tailoring through ligand coordination.

Charge-Transporting Materials for Perovskite Solar Cells

The power conversion efficiency of perovskite solar cells (PSCs) has been certified as ?22.1%, approaching the best single crystalline silicon solar cells. The improvement in the performance of PSCs could be achieved through the testing of novel materials in the device. This review briefly discusses the systematic introduction about several inorganic and organic electron-transporting materials (ETMs) and hole-transporting materials (HTMs) for efficient PSCs. The transport mechanism of electrons and holes in different ETMs/HTMs is also discussed on the basis of energy band diagrams with respect to the perovskite absorber. Moreover, the introduction of appropriate interfacial materials, hybrid ETMs, and doping is discussed to optimize the interfacial electronic properties between the perovskite layer and the charge-collecting electrode.

Electrodeposition of CuSCN seed layers and nanowires: A microelectrogravimetric approach

This paper analyzes the microelectrogravimetric aspects of CuSCN electrochemical deposition. Samples were prepared under conditions typically used during the first preparation step of the increasingly developed inverted photovoltaic cells, i.e., an approach based on the deposition of a hole transporting layer (p-type semiconductor) as a starting film. Here, both CuSCN seed layers and nanowires are the result of an electrodepositon process that uses electrolytes rich in Cu(II) species, thiocyanate ions and additives such as triethanolamine (TEA) or ethylenediaminetetraacetic acid (EDTA). Gold (Au) reactivity was compared to that of Indium Tin Oxide (ITO) coated quartz electrodes in the presence of aqueous thiocyanate ions. Consequently, ITO was confirmed as a suitable substrate for microelectrogravimetric purposes under conditions in which gold becomes electrochemically corroded. Both the speciation and the solubility diagrams for Cu(II) were prepared considering the presence of either TEA or EDTA as additives to establish the possible electroactive species involved in the electrochemical formation of CuSCN and its solubility as it grows. Following a potentiodynamic study and regardless of the additive used, it can be stated that CuSCN is accumulated on the electrode and is then reoxidized. The latter is accompanied by an almost complete loss of the previously accumulated mass. During the elapsed time of the experiments, two Cu(II) insoluble species, namely Cu(SCN)TEA and Cu(SCN)2, were stabilized as colloids in the employed electrolytes. These colloids can also participate as electroactive species in the CuSCN electroformation. However, for a better interpretation of results, more complete speciation diagrams are also required, but thermodynamic information on these species is still not available. During both potentiostatic and galvanostatic CuSCN growth, a CuSCN solubility effect may explain the slightly low faradaic efficiency of this process.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. category: copper-catalyst, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 1111-67-7, in my other articles.

Synthesis, characterization, and X-ray crystal structures of copper(I) halide and pseudohalide complexes with 2-(2-quinolyl)benzothiazole. Diverse coordination geometries and electrochemical properties

Three new copper(I) complexes with the ligand 2-(2-quinolyl)benzothiazole (qbtz) have been synthesized and characterized by elemental analyses, infrared, and ultraviolet?visible spectroscopy, and their crystal structures have been determined by X-ray diffraction. The coordination geometry around copper in [Cu(qbtz)(mu-I)]2, complex (1), a centrosymmetric dimer, is a distorted CuI2N2 tetrahedron supplemented by a short Cu?Cu interaction of 2.5855 A. The copper(I) cyanide?bridged complex [Cu3(qbtz)2(mu-CN)3] (2) exhibits a one-dimensional chain structure with three crystallographically independent Cu atoms. Two of the copper atoms feature tetrahedral four coordination each by a chelating qbtz ligand and two CN groups, and the third features a quasi-linear two-coordination geometry by two CN. In [Cu(qbtz)(mu-SCN)] (3), copper is in a distorted tetrahedral coordination by two N atoms of a chelating qbtz ligand and by one N atom and one S atom of a bridging SCN group. The complex exhibits a one-dimensional zigzag chain structure with two crystallographically inequivalent Cu atoms in the chain. The spectroscopic and electrochemical properties of compounds 1?3 are in accord with the variation in copper(I) coordination environments.

Highly efficient perovskite light-emitting devices containing a cuprous thiocyanate hole injection layer

Inorganic charge transporting materials offer numerous advantages over their organic counterparts, including high charge carrier mobility, stability, simple preparation, and low cost, and have been studied for perovskite optoelectronic devices. However, the majority of these materials strongly quench perovskite luminescence, which is detrimental to the performance of perovskite light-emitting devices. To overcome this and obtain good quality perovskite films, an organic interlayer modified with UV ozone is used. The effects of the UV ozone treatment on the energetics and chemical structures of the organic interlayer are examined. On the basis of this strategy, we fabricate perovskite light-emitting devices that contain a cuprous thiocyanate hole injection layer, which exhibit an improved external quantum efficiency of 10.2% and greater operational stability when compared with the devices that contain a conducting-polymer hole injection layer.
