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.

METAL PSEUDOHALIDE COMPLEXES, VI. COPPER(I) AZIDE COMPLEXES WITH SOME PYRIDINE DERIVATIVES, EXAMPLES OF END-TO-END BRIDGING AZIDES

A series of stable, coloured and diamagnetic copper(I) azido complexes of the type CuLnN2, where L=3-, and 4-CHO-py, 2-, 3-, and 4-COCH3-py, 2-, 3-, and 4-COOCH3-py, 2-, 3-, and 4-COOC2H5-py, 2-COC6H5-py and 4-CN-py, n=1 or 2, in addition to some new CuL2(NCS) complexes have been isolated and characterized.All these carbonyl ligands act as monodentate ones in the isolated complexes.IR results suggest that the azide groups in the isolated azido complexes act as bridging ligands through the two end nitrogen atoms.CuL2(NCS) complexes have almost distorted tetrahedral geometry through bridging thiocyanate groups.

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.
