Bright green-to-yellow emitting Cu(i) complexes based on bis(2-pyridyl)phosphine oxides: Synthesis, structure and effective thermally activated-delayed fluorescence

A family of brightly luminescent dinuclear complexes of [Cu(mu2-X)(N^N)]2 type (X = I or SCN) has been synthesized in 76-90% yields by the reaction of bis(2-pyridyl)phosphine oxides (N^N) with the corresponding Cu(i) salts. The X-ray diffraction study reveals that the Cu2I2 core of the [Cu(mu2-I)(N^N)]2 complexes has either a butterfly- or rhomboid-shaped structure, while the eighth-membered [Cu(SCNNCS)Cu] ring in the [Cu2(SCN)2(N^N)]2 complexes is nearly planar. In the solid state, these compounds exhibit a strong green-to-yellow emission (lambdaemmax = 536-592 nm) with high PLQYs (up to 63%) and short lifetimes (1.9-10.0 mus). The combined photophysical and DFT study indicates that the ambient-temperature emission of the complexes obtained can be assigned to the thermally activated-delayed fluorescence (TADF) from the 1(M + X)LCT excited state, while at 77 K, phosphorescence from the 3(M + X)LCT state is likely observed.

Microstructures, optical and photovoltaic properties of CH3NH3PbI3(1-x)Clx perovskite films with CuSCN additive

Microstructures, optical and photovoltaic properties of CH3NH3PbI3(1-x)Clx perovskite films with copper(I) thiocyanate (CuSCN) additive were investigated. The CuSCN-added CH3NH3PbI3(1-x)Clx films were prepared by a hot air blow-assisted spin-coating method. Current density-voltage characteristics of the photovoltaic device using the CuSCN-added CH3NH3PbI3(1-x)Clx light-absorbing layer showed increases in short-circuit current density, open-circuit voltage, which resulted in increase in the conversion efficiency. Microstructure analysis showed that the crystal structure of the CuSCN-added CH3NH3PbI3(1-x)Clx was a pseudocubic system. From these results, partial substitutions of Pb2+ and anions (I- and Cl-) by Cu ions (Cu+ and Cu2+) and SCN-, respectively, are considered to occur in the CuSCN-added CH3NH3PbI3(1-x)Clx films. Based on the obtained results, reaction mechanisms of the CH3NH3PbI3(1-x)Clx films with and without CuSCN additive were discussed.

Copper-Catalyzed Silylation of C(sp3)-H Bonds Adjacent to Amide Nitrogen Atoms

A copper-catalyzed C-Si bond formation between N-halogenated amides and Si-B reagents is described. This oxidative coupling enables the silylation of C(sp3)-H bonds alpha to an amide nitrogen atom. The utility of the new method is demonstrated for sulfonamides, and N-chlorination with tBuOCl and C-H silylation employing CuSCN/4,4?-dimethoxy-2,2?-bipyridine as catalyst can be performed without purification of the N-Cl intermediate.

Bridging homogeneous and heterogeneous catalysis with MOFs: Cu-MOFs as solid catalysts for three-component coupling and cyclization reactions for the synthesis of propargylamines, indoles and imidazopyridines

Copper-containing MOFs are found to be active, stable and reusable solid catalysts for three-component couplings of amines, aldehydes and alkynes to form the corresponding propargylamines. Two tandem reactions, including an additional cyclization step, leads to the effective production of indoles and imidazopyridines. In particular, the lamellar compound [Cu(BDC)] (BDC = benzene dicarboxylate) is highly efficient for the preparation of imidazopyridines, although a progressive structural change of the solid to a catalytically inactive compact structure is produced, causing deactivation of the catalyst. Nevertheless, the phase change can be reverted by refluxing in DMF, which recovers the original lamellar structure and the catalytic activity of the fresh material. The use of [Cu(BDC)] for this reaction also prevents the formation of Glaser/Hay condensation products of the alkyne, even when the reaction is performed in air atmosphere. This is a further advantage of [Cu(BDC)] with respect to other homogeneous copper catalysts, for which the use of an inert atmosphere is necessary.

We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of 13395-16-9, and how the biochemistry of the body works.Computed Properties of C10H16CuO4

Perovskites photovoltaic solar cells: An overview of current status

Perovskite based solar cells have recently emerged as one of the possible solutions in the photovoltaic industry for availing cheap solution processable solar cells. Hybrid perovskites display special combination of low bulk-trap densities, ambipolar charge transport properties, good broadband absorption properties and long charge carrier diffusion lengths, which make them suitable for photovoltaic applications. The year 2015 witnessed an upsurge in the published research articles on perovskite solar cells (PSC) which is indicative of the potential of this material. Since the introduction of PSC the power conversion efficiency has reached above 22% in a relatively short period of time. However, the poor reproducibility in device fabrication and lack of uniformity of the PSCs performances is a major challenge in obtaining highly efficient large scale PSC devices. The aim of this paper is to present a brief review on the current status of perovskites based solar cell due to the use of different device architectures, fabrication techniques as well as on the use of various electron and hole interfacial layers (HTMs and ETMs). The review also discusses the basic mechanisms for device operation which provides better understanding on the properties of the various layers of device structures.

Syntheses, structures, and luminescence properties of two copper(I) thiocyanate coordination polymers with different N-donor ligands

Two coordination polymers, [Cu(SCN)(3-ptz)]n(1) and [Cu(SCN)(btmb)]n¡¤nCH3CN (2) (3-ptz = 5-(3-pyridyl)tetrazole, btmb = 1,4-bis(1,2,4-triazol-1-ylmethyl)benzene), were synthesized and characterized by EA, IR, PXRD and thermogravimetry. Complex 1 is a 2-D coordination polymer constructed from bidentate 3-ptz and 1,3-thiocyanate ligands. Complex 2 is a 2-D wave-like coordination polymer assembled by bidentate btmb and 1,3-thiocyanate ligands. Acetonitrile guest molecule is perched in the tunnel. Complexes 1 and 2 remain stable up to 240C and 280C, respectively. Complex 1 emits strong orange luminescence at 590 nm, and complex 2 emits blue luminescence at 468 nm.

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.Product Details of 1111-67-7, you can also check out more blogs about1111-67-7

Carbon coated TiO2 nanoparticles prepared by pulsed laser ablation in liquid, gaseous and supercritical CO2

We report on the synthesis of TiO2 nanoparticles using nanosecond pulse laser ablation of titanium in liquid, gaseous and supercritical CO2. The produced particles were observed to be mainly anatase-TiO2 with some rutile-TiO2. In addition, the particles were covered by a carbon layer. Raman and x-ray diffraction data suggested that the rutile content increases with CO2 pressure. The nanoparticle size decreased and size distribution became narrower with the increase in CO2 pressure and temperature, however the variation trend was different for CO2 pressure compared to temperature. Pulsed laser ablation in pressurized CO2 is demonstrated as a single step method for making anatase-TiO2/carbon nanoparticles throughout the pressure and temperature ranges 5-40 MPa and 30 C-50 C, respectively.

A novel two-dimensional CuSCN network templated by 2,2?-dimethyl-1, 1?-(butane-1,4-diyl)bis(1H-imidazol-3-ium) cations

The cation-templated self-assembly of 1,4-bis(2-methyl-1Himidazol-1-yl) butane (bmimb) with CuSCN gives rise to a novel two-dimensional network, namely catena-poly[2,2?-dimethyl-1,1?-(butane-1,4-diyl)bis(1H-imidazol-3- ium) [tetra-mu2-thiocyanato-kappa4S: S;kappa4S:N-dicopper(I)]], {(C12H20N 4)[Cu2-(NCS)4]}n. The CuI cation is four-coordinated by one N and three S atoms, giving a tetrahedral geometry. One of the two crystallographically independent SCN- anions acts as a mu2-S:S bridge, binding a pair of CuI cations into a centrosymmetric [Cu2(NCS)2] subunit, which is further extended into a twodimensional 44-sql net by another kind of SCN – anion with an end-to-end mu2-S:N coordination mode. Interestingly, each H2bmimb dication, lying on an inversion centre, threads through one of the windows of the two-dimensional 44-sql net, giving a pseudorotaxane-like structure. The two-dimensional 44-sql networks are packed into the resultant three-dimensional supramolecular framework through bmimb-SCN N-H…N hydrogen bonds.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.

About a synthetic saliva for in vitro studies

Numerous artificial salivas have been used during studies in odontology. These salivas have compositions, which are more or less the same as that of natural saliva. In this article, we are presenting a discussion about the various media described in the related literature. A review of nearly 60 artificial salivas was carried out to clarify the role of some of the compounds most frequently met in the proposed formulae. The study focused on the buffer effect, the role played by CO2 gas and the presence of calcium ions, hydrogenocarbonates, hydrogenophosphates and thiocyanates. The SAGF medium, which we proposed some years ago, was used as a reference and some in vitro behavioral tests of dental biomaterials were studied in a comparative way. Using the SAGF medium allowed us to specify the mode of fluoride ions release from glass ionomer cements and the corrosion behavior of the dental amalgams.
