Nine novel copper(I) complexes with diphosphine and diimine ligands, namely [Cu(dpq)(xantphos)]BF4 (1), [Cu(dpq)(xantphos)]I (2), [Cu(dpq)(dppp)]BF4 (3), [Cu(dppz)(dppp)]BF4 (4), [Cu(dppz)(dppp)]I (5), [Cu(dppz)(pop)]I (6), [Cu(dpq)(pop)]I (7), [Cu(dpq)(pop)]Br (8), [Cu(dpq)(pop)]SCN (9) (dpq = pyrazino[2,3-f][1,10]phenanthroline, dppz = dipyrido[3,2-a:2?,3?-c]phenazine, xantphos = 9,9-dimethyl-4,5-bis(diphenylphosphanyl)xanthene, dppp = 1,3-bis(diphenylphosphino)propane, pop = 1,1?-[(Oxydi-2,1-phenylene)]bis[1,1-diphenylphosphine]), were characterized by single crystal X-ray diffraction, IR, elemental analysis, 1H NMR, 31P NMR, fluorescence spectra and terahertz time domain spectroscopy (THz-TDS). These nine complexes were synthesized by the reactions of copper salts, diimine ligands and various of P-donor ligands through one-pot method. Single crystal X-ray diffraction reveals that complex 9 is of a simple mono-nuclear structure while complexes 6 and 7 are of dimer structures. For complex 8, hydrogen bonds and C?H?pi interactions lead to the formation of a 1D infinite chain structure. Interestingly, complexes 1?5 show novel 2D or 3D network structures through C?H?pi interactions. In addition, complexes 1?3 and 6?9 exhibit interesting fluorescence in the solid state at room temperature. Among the nine complexes, complex 1 shows the highest quantum yield up to 37% and the lifetime of 1 is 6.0 mus. The terahertz (THz) time-domain spectra of these complexes were also studied.

Thiolate self-assembly on gold has proven to be a valuable technique for assembling monolayers on a wide variety of substrates. However, the oxidative instability of the thiols, especially aromatic thiols and alpha,omega-dithiols, presents several difficulties. Shown here is that thiocyanates, easily synthesized stable thiol derivatives, can be directly assembled on gold surfaces with no auxiliary reagents required. Assembly is complete in 24 h and leaves a similar gold thiolate structure as seen in typical thiol self-assembled monolayers. Copyright

Copper thiocyanate (CuSCN) has recently received considerable attention because of its high hole mobility and applications in solar cells [Science 358(2017)768]. In this work, by performing state-of-the-art theoretical calculations, for the first time we find that the thermal conductivities of both alpha- and beta-CuSCN are ultralow with the values of 1.2 and 2.4 W/mK at room temperature, respectively. Based on detailed analyses of the phonon dispersion, Grueneisen parameters, three phonon scattering rates and atomic displacement parameters, we further demonstrate that the underlying reasons for the ultralow thermal conductivities are due to the avoided crossing between the longitudinal acoustic (LA) phonons and the low-lying optical branches as well as the weak bonding and strong anharmonicity. The low lattice thermal conductivities lead to high ZT values of 1.7 and 2.1 at 800 K for alpha- and beta-CuSCN, respectively. In addition, both materials exhibit large negative thermal expansion (NTE) coefficients originated from the transverse vibrations in Cu?N?C?S chains. These features endow CuSCN with the potential for thermal barrier coating and thermal devices going beyond the reported photovoltaic applications.
