A method is found to significantly improve the p-type conductivity of CuSCN modified by incorporating triethylamine coordinated Cu(II) sites in its structure. It is done by mixing triethylamine hydrothiocyanate with CuSCN in propyl sulfide solution and allowing it to stand still in the dark for a few weeks in a closed sample tube. XRD and SEM analyses point to the modification of the CuSCN material. The Hall effect measurements clearly show a significant enhancement of hole concentration and hence of p-type conductivity. A maximum conductivity of 1.42 S m?1 is achieved for the structurally modified CuSCN compared to that of 0.01 S m?1 for ordinary CuSCN. AC impedance analysis of solid-state dye-sensitized solar cells based on this material clearly shows the reduction of bulk resistance of the cell with the use of modified CuSCN. This decrease in resistance has been attributed to the enhancement of conductivity and better pore filing of modified CuSCN inside the TiO2 matrix. As such, the solar cell performance gradually increases to an optimum value beyond which it decreases. The best result obtained for conversion efficiency is 3.4% at AM 1.5, which is a 41.8% enhancement from the best reported value for a dye-sensitized solid-state solar cell using CuSCN as a hole conducting material. The best efficiency value obtained is 14 times higher than that obtained for the dye-sensitized solid-state solar cell made with ordinary CuSCN.

The reaction of a C3-symmetric tridentate ligand, N,N?,N?-(4,4?,4?-nitrilotris(4,1-phenylene)) triisonicotinamide (L), with various d10-metal salts of CuI, Cu(SCN), and M(ClO4)2 (M = Zn, Cd) led to four metal-organic materials of {[(Cu2I2)(L)2] ·4DMF·2MeOH}n (1), {[Cu(L)2(NCS) 2]·3DMF}n (2), and {[M(L)2(ClO 4)2]·4EtOH}n (M = Zn 3 and Cd 4), respectively, which have been isolated and structurally characterized by X-ray diffraction studies. The X-ray analysis revealed that the interlocking of the 1-D double-zigzag chains of 1-4 into the macrocycles of the adjacent chains generates a novel 2-D (1-D ? 2-D) polyrotaxane framework. In these 2-D polyrotaxane frameworks, the C3-symmetric tridentate ligand, L, only adopts a mu2-bridging mode, and the third arm is free. In addition, 1-4 are all emissive with dual emissions (431-452 and 558-570 nm) in the solid state at room temperature and at 77 K, which are suggested to be due to an intraligand transition of L based on the high similarities in emission energies to that of L.

The series of chelating phosphine ligands, which contain bidentate P2 (bis[(2-diphenylphosphino)phenyl] ether, DPEphos; 4,5-bis(diphenylphosphino)-9,9-dimethylxanthene, Xantphos; 1,2-bis(diphenylphosphino)benzene, dppb), tridentate P3 (bis(2-diphenylphosphinophenyl)phenylphosphine), and tetradentate P4 (tris(2-diphenylphosphino)phenylphosphine) ligands, was used for the preparation of the corresponding dinuclear [M(mu2-SCN)P2]2 (M = Cu, 1, 3, 5; M = Ag, 2, 4, 6) and mononuclear [CuNCS(P3/P4)] (7, 9) and [AgSCN(P3/P4)] (8, 10) complexes. The reactions of P4 with silver salts in a 1:2 molar ratio produce tetranuclear clusters [Ag2(mu3-SCN)(t-SCN)(P4)]2 (11) and [Ag2(mu3-SCN)(P4)]22+ (12). Complexes 7-11 bearing terminally coordinated SCN ligands were efficiently converted into derivatives 13-17 with the weakly coordinating -SCN:B(C6F5)3 isothiocyanatoborate ligand. Compounds 1 and 5-17 exhibit thermally activated delayed fluorescence (TADF) behavior in the solid state. The excited states of thiocyanate species are dominated by the ligand to ligand SCN ? pi(phosphine) charge transfer transitions mixed with a variable contribution of MLCT. The boronation of SCN groups changes the nature of both the S1 and T1 states to (L + M)LCT d,p(M, P) ? pi(phosphine). The localization of the excited states on the aromatic systems of the phosphine ligands determines a wide range of luminescence energies achieved for the title complexes (lambdaem varies from 448 nm for 1 to 630 nm for 10c). The emission of compounds 10 and 15, based on the P4 ligand, strongly depends on the solid-state packing (lambdaem = 505 and 625 nm for two crystalline forms of 15), which affects structural reorganizations accompanying the formation of electronically excited states.

New late-stage phosphorothiolation methods are disclosed that allow the efficient transfer of SP(O)(OR)2 groups to diversely functionalized substrates using nucleophilic and electrophilic reagents. The nucleophilic reagent, tetramethylammonium O,O-dimethyl phosphorothioate, was synthesized in near-quantitative yield from Me3SiP(O)(OMe)2, elemental sulfur and Me4NF. Its umpolung with N-bromophthalimide provided the electrophilic reagent, O,O-dimethyl-S-(N-phthalimido)phosphorothioate. Complementary methods based on these reagents enable the phosphorothiolation of diversely functionalized alkyl halides, arenediazonium salts, arylboronic acids and electron-rich arenes in good yields under mild conditions.

The invention provides a novel process for producing a 3,5-difluoroaniline compound by reacting a 2-halo-4,6-difluoroaniline with a diazotizing agent in the presence of a reducing agent to form a diazonium salt. Build-up of potentially dangerous diazonium salt is avoided by reducing the diazonium salt with the reducing agent, to form a 1-halo-3,5-difluorobenzene, contemporaneously with the diazotization reaction. The 1-halo-3,5-difluorobenzene is then aminated.

Wide bandgap hole-transporting semiconductor copper(I) thiocyanate (CuSCN) has recently shown promise both as a transparent p-type channel material for thin-film transistors and as a hole-transporting layer in organic light-emitting diodes and organic photovoltaics. Herein, the hole-transport properties of solution-processed CuSCN layers are investigated. Metal-insulator-semiconductor capacitors are employed to determine key material parameters including: dielectric constant [5.1 (±1.0)], flat-band voltage [-0.7 (±0.1) V], and unintentional hole doping concentration [7.2 (±1.4) × 1017 cm-3]. The density of localized hole states in the mobility gap is analyzed using electrical field-effect measurements; the distribution can be approximated invoking an exponential function with a characteristic energy of 42.4 (±0.1) meV. Further investigation using temperature-dependent mobility measurements in the range 78-318 K reveals the existence of three transport regimes. The first two regimes observed at high (303-228 K) and intermediate (228-123 K) temperatures are described with multiple trapping and release and variable range hopping processes, respectively. The third regime observed at low temperatures (123-78 K) exhibits weak temperature dependence and is attributed to a field-assisted hopping process. The transitions between the mechanisms are discussed based on the temperature dependence of the transport energy. The wide bandgap p-type semiconductor copper(I) thiocyanate (CuSCN) has the potential to replace conventional hole-transport materials in numerous opto/electronics applications. This work provides a comprehensive analysis of the charge transport properties of solution-processed CuSCN layers. Various techniques are employed to evaluate the dielectric constant, flat-band voltage, unintentional doping concentration, density of states in the mobility gap, and hole-transport mechanisms.
