Network Motifs and Thermal Properties of Copper(I) Halide and Pseudohalide Coordination Polymers with 1,7- and 4,7-Phenanthroline

The coordination polymers .infin.(1)[CuBr(1,7-phen-kappaN7)] (1a), [CuI(1,7-phen)] (2a) and [(CuI)2(1,7-phen-kappaN7)] (2b) may be prepared by treatment of the appropriate copper(I) halide with 1,7-phenanthroline(1,7-phen) in acetonitrile. 1a exhibits staircase CuBr double chains, 2 a novel quadruple CuI chains. Their thermal properties were investigatedby DTA-TG and temperature resolved powder X-ray diffraction. On heating , both 1:1 compounds decompose to 2:1 polymers and then finally to CuBr or CuI. With 4,7-phenanthroline (4,7-phen), CuBr affords both 1:1 and 2:1 complexes (5a, 5b), CuI 1:1, 2:1 and 3:1 complexes (6a, 6b, 6c) in acetonitrile at 20¡ãC. 5a and 6a display lamellar coordination networks, with the former containing zigzag CuBr single chains, the latter 4-membered (CuI)2 rings. A second 2:1 complex .infin.(2)[(CuI)2(4,7-phen-mu-N4,N7)] (6b’) with staircase CuI double chains can be obtained by reacting CuI with 4,7-phen in a sealed glass tube at 110¡ãC. Both 5a and 6a exhibit thermal decomposition pathways of the general type 1:1 2:1 3:1 CuX, and novel CuX triple chains are proposedfor the isostructural 3:1 polymers 5c and 6c. X-ray structures are repo rted for complexes 1a, 2b, .infin(2)[(CuCN)3(CH3CN)(1,7-phen-mu-N1,N7)] (3c*CH3CN), .infin.(1)[CuSCN(1,7-phen-kappaN7)] (4a), 5a, 6a and .infin.(2)[CuCN(4,7-phen-mu-N4,N7)] (7a).

Annealing Solution-Processed CuSCN Hole Injection Layer for Blue Phosphorescent Organic Light-Emitting Diodes with Extremely Low Efficiency Roll-Off

Phosphorescent organic light-emitting diodes (PhOLEDs) have attracted tremendous attention recently but still suffer serious efficiency roll-off at high luminance, which will significantly limit their practical application in the future. Here, using a spin-coated transparent CuSCN film as the hole-injection layer (HIL), we succeed in achieving high-performance blue PhOLEDs with extremely low efficiency roll-offs based on widely used host and guest materials in a conventional device structure; by thermal and current annealing treatments, the external quantum efficiency (EQE) is up to 12.5% at 8370 cd m-2, and the EQE roll-off can be as low as 2% at 10 000 cd m-2 and 7% at 20 000 cd m-2, respectively. The inorganic molecular semiconductor feature of CuSCN and the improved hole mobility after the annealing treatment were proved to be the main reasons for the highly stable PhOLEDs. The successful application of solution-processed CuSCN HIL for blue PhOLEDs with low efficiency roll-offs could provide important guidelines for the development of low-cost and highly efficient devices at high luminance.

Construction of copper-based coordination polymers with 1D chain, 2D plane and wavy networks: Syntheses, structures, thermal behavior and photoluminescence properties

Three Cu-based coordination polymers (CPs), including [Cu II(N- eta 1-NCS) 2(O- eta 1-DMF) 2(mu 2-3,3′-bptz)] n (1), [Cu I(1,3- mu 2-NCS)(mu 2-3,3′-bptz)] n (2) and [(Cu I(1,3- mu 2- NCS))(mu 2-4,4′-bptz)] n (3) (DMF = N, N-dimethyl formamide, 3,3′-bptz = 3,6-bis(3-pyridyl)tetrazine and 4,4′-bptz = 3,6-bis(4-pyridyl)tetrazine) have been successfully constructed by solution diffusion reactions by using Cu(NO 3) 2.3H 2O or CuNCS and KNCS with 3,3′-bptz / 4,4′-bptz ligands, respectively. The resulting crystalline materials have been characterized by the single-crystal X-ray diffraction analyses, elemental analyses, FT-IR spectra, thermogravimetric analyses and powder X-ray diffraction (PXRD). Single crystal X-ray analyses revealed that CP 1 is organized in one-dimensional (1D) chain in which the Cu(II) ions are coordinated by eta 1-NCS – anions and eta 1-DMF molecules, and linked by mu 2-3,3′-bptz bridging ligands. CPs 2 and 3 are structural isomers. CP 2 exhibits two-dimensional (2D) (4,4)-plane-like network in which Cu(I) ions are linked by mu 2-NCS – and mu 2-3,3′-bptz ligands. In CP 3, Cu(I) ions are connected by mu 2-NCS – and mu 2-4,4′-bptz ligands to form 2D saw-tooth wavy network. In addition, the photoluminescence properties of CPs 1-3 were also investigated in the solid state at room temperature.

Dependence of Tc on hydrostatic pressure in beta?-(ET)2SF5CH2CF2SO 3 and kappa-(ET)2Cu(NCS)2

The dependence of Tc on hydrostatic (He-gas) pressure is determined for the recently discovered organic superconductor beta?-(ET)2SF5CH2CF2SO 3 [ET = bis(ethylenedithio)-tetrathiafulvalene] with Tc(0) ? 5 K, yielding the pressure derivative dTc/dP ? -1.34 K kbar-1. The present experiments also included kappa-(ET)2Cu(NCS)2 where we find the extremely large value dTc/dP ? -3.84 K kbar-1, in agreement with earlier studies. For both samples the pressure dependence Tc(P) does not depend on the temperature at which the pressure is changed.

Assembly of novel 2D and 3D heterometallic SbIII-CuI polymers based on antimony(III) thiolates as metallothiolato ligands

A new type of neutral heterometallic SbIII-CuI thiolate coordination polymer has been synthesized under solvothermal conditions by using antimony(III) thiolates as metalloligands and CuSCN as the source of the second metal ion. Reaction of [Sb(edt)Cl] (1) (edt = ethane-1,2-dithiolate) with 1 equivalent of CuSCN affords [{Sb2(edt) 2(mu3-S)CuCl(CuSCN)}n] (2), which features a 2D layer consisted of -CuSCNCuSCN-chains and {Sb2(edt) 2(mu3-S)CuCl} units. During the reaction, 1 was converted into a sulfur-bridged dimer Sb(edt)2S, which behaves simultaneously as a bridging and chelating ligand through all of its sulfur atoms to connect four Cu+ ions in the framework structure of 2. Replacement of Cl- in 1 with pymt-gives a new antimony(III) thiolate formulated as [Sb(edt)-(pymt)] (3) (pymt = 2-pyrimidinethiol), which was further treated with CuSCN to afford coordination polymers [{[Sb(edt)(pymt)] 2(CuSCN)3}n] (4) and [{[Sb(edt)(pymt)]-(CuSCN) 2}n] (5). In the assemblies of 4 and 5, the structure of 3 remains intact and the whole compound serves as a multidentate ligand through Sedt and Npymt atoms to Cu+ ions. Complex 4 also contains -CuSCNCuSCN- chains, which are linked by tridentate {Sb(edt)(pymt)} fragments to form a 2D polymer. Complex 5 is a 3D architecture with {Sb(edt)(pymt)} units acting as bidentate bridging ligand to link the (CuSCN)n layers and {(CuSCN)2}n columns. Complexes 2-5 showed optical transitions with band gaps of 2.66 to 3.41 eV, and their optical properties were studied by DFT calculations. Wiley-VCH Verlag GmbH & Co. KGaA, 2009.

Stability of organometal halide perovskite solar cells and role of HTMs: Recent developments and future directions

Perovskite solar cells (PSCs) have recently emerged as one of the most exciting fields of research of our time, and the World Economic Forum in 2016 recognized them as one of the top 10 technologies in 2016. With 22.7% power conversion efficiency, PSCs are poised to revolutionize the way power is produced, stored and consumed. However, the widespread use of PSCs requires addressing the stability issue. Therefore, it is now time to focus on the critical step i.e. stability under the operating conditions for the development of a sustainable and durable PV technology based on PSCs. In order to improve the stability of PSCs, hole transport materials (HTMs) have been considered as the paramount components. This is due to the fact that most of the organic HTMs possess a hygroscopic and acidic nature that leads to poor stability of the PSCs. This article reviews briefly but comprehensively the environmental stability issues of PSCs, fundamentals, strategies for improvement, the role of HTMs towards stability and various types of HTMs. Also the environmental parameters affecting the performance of perovskite solar cells including temperature, moisture and light soaking environment have been considered.

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.
