Polyrotaxane frameworks containing N,N?,N?-(4,4?, 4?-nitrilotris(4,1-phenylene))triisonicotinamide: Structural and luminescent properties

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.

A Novel, Nonelectrochemical Synthesis of the Organic Superconductor kappa-(BEDT-TTF)2Cu(NCS)2

Bis(ethylendithio)tetrathiafulvalene (BEDT-TTF or ET) can be oxidized with Cu(SCN)2 to yield superconducting, microcrystalline kappa-(ET)2CU(NCS)2.The reaction is achieved either by heating a suspension of the reactants in various organic solvents or by ultrasound agitation at room temperature.The formation of the title compound was established by X-ray diffractograms, FT-IR and ESR spectroscopy.Susceptibility measurements revealed superconducting transition temperatures of 9.5-10 K.The clearly observed Meissner effect suggests superconductivity to be a bulk property of the so-obtained powder samples.

Synthesis and structural characterization of six pentanuclear and tetranuclear Mo/W-Cu-S clusters with BIS(Diphenylphosphanyl) methane

Six heterothiometalic clusters, namely,[WS4Cu4(dppm)4]-(ClO4)2?2DMF?MeCN (1), [MoS4Cu4(dppm)4](NO3)2?MeCN (2) [MoS4Cu3(dppm)3](ClO4)?4H2O (3), [WS4Cu3(dppm)3](NO3)?4H2O (4), [WS4Cu3(dppm)3]SCN?CH2Cl2 (5), and [WS4Cu3(dppm)3]I?CH2Cl2 (6) [dppm = bis (diphenylphosphanyl)methane] were synthesized. Compounds 1?4 were obtained by the reactions of (NH4)2MS4 (M = Mo, W) with [Cu2(mu2-dppm)2(MeCN)2(ClO4)2] {or [Cu(dppm)(NO3)]2} in the presence of 1,10-phen in mixed solvent (CH3CN/CH2Cl2/DMF for 1 and 2, CH2Cl2/CH3OH/DMF for 3 and 4. Compounds 5 and 6 were obtained by one-pot reactions of (NH4)2WS4 with dppm and CuSCN (or CuI) in CH2Cl2/CH3OH. These clusters were characterized by single-crystal X-ray diffraction as well as IR,1H NMR, and31P NMR spectroscopy. Structure analysis showed that compounds 1 and 2 are ?saddle-shaped? pentanuclear cationic clusters, whereas compounds 3?6 are ?flywheel-shaped? tetranuclear cationic clusters. In 1 and 2, the MS42- unit (M = W, Mo) is coordinated by four copper atoms, which are further bridged by four dppm molecules. In compounds 3?6, the MS42- unit is coordinated by three copper atoms and each copper atom is bridged by three dppm ligands.

Donor?Acceptor-Conjugated Polymer for High-Performance Organic Field-Effect Transistors: A Progress Report

Polymeric semiconductors have demonstrated great potential in the mass production of low-cost, lightweight, flexible, and stretchable electronic devices, making them very attractive for commercial applications. Over the past three decades, remarkable progress has been made in donor?acceptor (D?A) polymer-based field-effect transistors, with their charge-carrier mobility exceeding 10 cm2 V?1 s?1. Numerous molecular designs of D?A polymers have emerged and evolved along with progress in understanding the charge transport physics behind their high mobility. In this review, the current understanding of charge transport in polymeric semiconductors is covered along with significant features observed in high-mobility D?A polymers, with a particular focus on polymeric microstructures. Subsequently, emerging molecular designs with further prospective improvements in charge-carrier mobility are described. Moreover, the current issues and outlook for future generations of polymeric semiconductors are discussed.

Toward Long-Term Stable and Highly Efficient Perovskite Solar Cells via Effective Charge Transporting Materials

Perovskite solar cells (PSCs) have advanced quickly with their power conversion efficiency approaching the record of silicon solar cells. However, there is still a big challenge to obtain both high efficiency and long-term stability for future commercialization of PSCs. The major instability issue is associated with the decomposition or phase transition of perovskite materials that are believed to be intrinsically unstable under outdoor working conditions. Herein, the authors review the approaches that marked important progress in developing new functional electron/hole transporting materials that enabled highly efficient and stable PSCs. The findings that accelerate charge diffusion and that suppress the irrevocable loss of ions diffusing out of perovskite materials and other diffusion processes are highlighted. In addition, derivative interface engineering methods to control the diffusion process of charges/ions/molecules are also reviewed. Finally, the authors propose key research issues in charge transporting materials and interface engineering with regard to the important diffusion processes that will be one of the keys to realize highly efficient and long-term stable PSCs.

High-Performance P-Type Copper(I) Thiocyanate Thin Film Transistors Processed from Solution at Low Temperature

Semiconducting copper(I) thiocyanate (CuSCN) is actively studied for electronic and optoelectronic applications. Although various kinds of CuSCN-based transistors are reported, these devices suffer from low charge carrier mobility of about 0.01?0.1 cm2 V?1 s?1. Here, ion gel electrolyte consisting of network polymer and ionic liquid is used as a high capacitance gate insulator to achieve high performance CuSCN-based electrolyte-gated transistors (CuSCN-EGTs) with low operation voltage below 1 V. 30 nm thick CuSCN semiconductor film can be formed by a simple solution process with a low processing temperature (?100 C) that is directly applicable to flexible plastic substrates. By doping copper iodide to the CuSCN semiconductor, device performance including drain current and charge carrier mobility of the CuSCN EGT can be improved significantly. The measured charge carrier mobility of ?0.3 cm2 V?1 s?1 is the highest among the reported CuSCN transistors using various gate insulators. These CuSCN-EGTs also display good operation stability under continuous quasistatic external gate voltage sweeps. Such superior electrical performance and versatile processability of ion gel?gated CuSCN transistors make them suitable for use in complimentary circuits and large-area flexible electronics.
