Exocyclic coordination chemistry of an O2S2- macrocycle with copper(i), mercury(ii) and palladium(ii) ions

The preparation and structures of the exocyclic coordination-based supramolecular complexes of a 14-membered dibenzo-O2S 2-macrocycle, L, with thiaphilic soft metal ions Cu(i), Hg(ii) and Pd(ii) are reported. The X-ray crystal structures of the eight complexes have been determined, and a range of the less common structural types, including mono- and multinuclear species with discrete and infinite forms were obtained. L reacts with copper(i) halides and afforded isostructural complexes of type [(Cu2X2)L]n (1: X = Cl, 2: X = Br) adopting a two-dimensional (2-D) polymeric structure linked by square-type Cu 2X2 clusters, while copper(i) iodide gave a yellow emissive complex {[(Cu4I4)L2]·2.5H 2O}n (3) whose crystal structure was not available. Treatment of L with copper(i) thiocyanate gave an infinite 2-D coordination network [CuLSCN]n (4) in which copper atoms are linked by SCN – forming a 1-D backbone, then further cross-linked by Lvia Cu-S bonds resulting in a grid-type layered structure. Reactions of L with HgX 2 (X = Br and I) resulted in the formation of an interesting “ivy-leaves” shaped complex [HgLBr2]n (5) with a syndiotactic arrangement and a single-stranded complex [(Hg2I 4)L]n (6), respectively, adopting an infinite 1-D structure. Unlike the copper(i) and mercury(ii) complexes with the infinite structures, reactions of L with Pd(NO3)2 gave a 1:1 (metal-to-ligand) dinitrato complex cis-[PdL(NO3)2] (7) and a 1:2 bis(macrocycle) complex cis-[PdL2](NO3) 2 (8) in a discrete form depending on the molar ratio of the reactants. A straightforward one-pot reaction of Pd(NO3)2 with two equivalents of L also resulted in the isolation of the bis(macrocycle) complex 8. The comparative NMR and ESI-mass studies for the palladium(ii) complexes were also carried out. The results are discussed in terms of the exo-coordination modes as well as the anion coordination.

Transformation from Cu2-xS Nanodisks to Cu2-xS@CuInS2 Heteronanodisks via Cation Exchange

Cationic-exchange methods allow for the fabrication of metastable phases or shapes, which are impossible to obtain with conventional synthetic colloidal methods. Here, we present the systematic fabrication of heteronanostructured (HNS) Cu2-xS@CuInS2 nanodisks via a cationic-exchange reaction between Cu and In atoms. The indium-trioctylphosphine complex favorably attacks the lateral (16 0 0) plane of the roxbyite Cu2-xS hexagon. We explain the phenomena by estimating the formation energy of vacancies and the heat of reaction required to exchange three Cu atoms with an In atom via density functional theory calculations. In an experiment, a decrease in the amount of trioctylphosphine surfactant slows the reaction rate and allows for the formation of a lateral heterojunction structure of nanoplatelets. We analyze the exact structures of these materials using scanning transmission electron microscopy-energy dispersive X-ray spectroscopy and high-resolution transmission electron microscopy. Moreover, we demonstrate that our heteronanodisk can be an intermediate for different HNS materials; for example, adding gold precursors to a Cu2-xS@CuInS2 nanodisk results in a AuS@CuInS2 nanodisk via an additional cationic reaction between Cu ions and Au ions.

The reaction of the bidentate Schiff-base ligands (3,4,5-MeO-ba)2en (L1) and (4-Me-ba)2en (L2) with Cu(SCN) in CH3CN yielded two copper(I) coordination polymers [Cu(L1)(SCN)]n (1) and [Cu(L2)(SCN)]n (2), which have been characterized by elemental analyses, IR- and 1H NMR-spectroscopy, and X-ray crystallography. The non-centrosymmetric structures of both Cu(I) complexes consist of an one-dimensional polymeric chain in which copper(I) ions are bridged by two thiocyanate groups bonding in an end-to-end fashion.

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.

High-efficiency perovskite solar cell using cobalt doped nickel oxide hole transport layer fabricated by NIR process

Lead halide perovskite solar cells (PVSCs) have potential toward commercialization because of their high efficiency and low cost. The hole transport layer (HTL) of p-i-n perovskite solar cell is usually made of NiOX. However, the NiOX needs to be processed at 300 C for 15 min for good hole transport property. This long heating time prohibits the development of continuous commercial process. Thus, a rapid heating process for the NiOX film deposition is critical to realize the commercialization of PVSCs in the future. In this study, we develop a facile method to obtain high quality NiOX films annealed by NIR in a short time of 50 s. A short-wave NIR lamp at 2500 K was used to systematically investigate the effect of NIR intensity on the film quality of sol-gel NiOX. The PVSCs fabricated from NIR-annealed NiOX (NIR-NiOX) film show a comparable power conversion efficiency (PCE) to those fabricated from traditional hot-plate annealed-NiOX (HP-NiOX). In addition, the NIR annealed cobalt-doped NiOX (NIR-Co:NiOX) was synthesized to replace pristine NIR-NiOX. The PCE of PVSCs fabricated from this new NiOX film can be increased from 15.99% to 17.77%, which is due to the efficient hole extraction, less charge accumulation, and reducing Voc loss resulting from the improved hole mobility, reduced interface resistance and well-matched work function. Our study paves a way to fulfill the requirements of low cost and low energy consumption of large scale production of high efficiency PVSCs.
