Digital image analysis for measuring nanogap distance produced by adhesion lithography

A simple digital image analysis for measuring nanogap distance produced by adhesion lithography is proposed. Adhesion lithography produces metal electrodes with sub-15 nm undulated space and mum to mm scale width without using electron beam lithography. Although the process has been rapidly improved in recent years, there has been no generalized procedure to evaluate the nanogap distance. In this study, we propose a procedure to evaluate a nanogap electrode with large width/gap distance ratios (>1000). The procedure is to determine the average distance of nanogap space from the area and the perimeter of the space by the analysis of the grayscale image. This procedure excludes any arbitrariness of the estimation and gives quantitative comparison of nanogap electrodes produced by different processes.

The metal complexes of 1-(phenylamino)-4, 4, 6-trimethyl-3, 4-dihydropyrimidine-2-(1H)-thione: Preparation, physical, spectroscopic studies and antibacterial properties

Objective: The metal complexes of 1-(Phenylamino)-4, 4, 6-trimethyl-3, 4-dihydropyrimidine-2-(1H)-thione: preparation, physical and spectroscopic studies and preliminary antibacterial properties. Methods: Complexes of bidentate ligand containing N, S-bridge [M(pmpt)2(H2O)n] (M(II) = Cu, Mn, Ni, Co; n = 2 and M(II) = Zn, Cd, Pd; n = 0) derived from the reaction of Hpmpt ligand with metals (M(II) = Cu, Mn, Ni, Co, Zn, Cd, Pd) and characterized by various physico-chemical techniques. From magnetic moment studies, square planar geometry is suggested for Zn(II), Cd(II), Pd(II) complexes, octahedral geometry is proposed for Co(II), Ni(II) and Mn(II) and distorted octahedral for Cu(II) complexes. Thermo gravimetric (TG) curves indicate the decomposition of complexes in four to five steps. The presence of coordinated water in metal complexes was confirmed by thermal, elemental analysis and IR data. Free ligand and its complexes were assayed in vitro for their antibacterial activity against gram positive and gram negative bacteria using chloramphenicol as a standard market-drug. Results: The reported complexes were synthesized through greener protocol that is grindstone method by mixing the ligand and metal salts in 2:1 molar ratio. Products were obtained in good yield with sharp melting point. Conclusion: Studies have indicated that such complexes can be prepared by environment friendly approach which requires less time, simple workup for isolation and purification with good yield. The [Ni(pmpt)2(H2O)2] complex showed excellent antibacterial activity while other reported metal complexes showed weak antibacterial activity.

Transitionmetal complexes with pyrazole-based ligands: Part 21. Thermal decomposition of copper and cobalt halide complexes with 3,5-dimethyl-1- thiocarboxamidepyrazole

The thermal decomposition of Cu2L2Cl4, Cu2L2Cl2, Cu2L2Br 2 and Co2L2Cl4 complexes (L=3,5-dimethyl-1-thiocarboxamidepyrazole) is described. The influence of the central ion to ligand mole ratio on the course of complex formation is examined in reaction of L with copper(II) chloride. In Cu(II):L mole ratio of 1:1, in methanolic solution the reaction yields to yellow-green Cu2L 2Cl4 crystals. In the filtrate a thermodynamically more stable orange Cu2L2Cl2 copper(I) complex is forming. With a Cu(II):L mole ratio of 1:2 only the latter compound is obtained. The composition and the structure of the compounds have been determined on the basis of customary methods. On the basis of FTIR spectrum of the intermediate which is forming during the thermal decomposition of Cu2L 2Cl2 a decomposition mechanism is proposed.

Lamellar copper(I) thiocyanate-based coordination polymers containing the alkali cation ligating thiacrown ether 1,10-dithia-18-crown-6

The lamellar coordination polymer ?2[(CuSCN)2-(mu-1,10DT18C6)] (l,10DT18C6 = l,10-dithia-18-crown-6), in which staircase-like CuSCN double chains are bridged by thiacrown ether ligands, may be prepared in two triclinic modifications la and 1b by reaction of CuSCN with 1,10DT18C6 in respectively benzonitrile or water. Performing the reaction in acetonitrile in the presence of an equimolar quantity of KSCN leads, in contrast, to formation of the K+ ligating 2-dimensional thiocyanatocuprate(I) net ?2[{Cu2(SCN)3}-] of 2, half of whose Cu(I) atoms are connected by 1,10DT18C6 macrocycles. The potassium cations in ?2[{K(CH3CN)}{Cu2(SCN) 3(mu-l,10DT18C6)}] (2) are coordinated by all six potential donor atoms of a single thia crown ether in addition to a thiocyanate S and an acetonitrile N atom. Under similar conditions, reaction of Cul, NaSCN and 1,10DT18C6 affords ?2[{Na(CH3CN)2}{Cu 4I4(SCN)(mu-1,10DT18C6)}] (3), which contains distorted Cu4I4 cubes as characteristic molecular building units. These are bridged by thiocyanate and thiacrown ether ligands into corrugated Na+ ligating sheets. In the presence of divalent Ba2+ cations, charge compensation requirements lead to formation of discrete [Cu(SCN)3(1,10DT18C6-KS)]2- anions in ?2 [Ba{Cu(SCN)3(1,10DT18C6-KS)}] (4).

Triboluminescent Electrospun Mats with Blue-Green Emission under Mechanical Force

Fibrous mechanosensing elements can provide information about the direction of crack propagation and the mechanism of material failure when they are homogeneously dispersed into the bulk volume of materials. A fabrication strategy of fibrous systems showing triboluminescent (TL) responses is in high demand for such applications. In this work, micrometer-sized Cu(NCS)(py)2(PPh3) crystals were synthesized, and polymeric fibrous mats containing the TL crystals were obtained via electrospinning as a stress probe for the determination of mechanical impact. Four different polymeric systems have been employed (PMMA, PS, PU, and PVDF), and the mechano-optical sensing performance of electrospun mats of the polymer-crystal composites was measured. Photophysical properties (quantum yield, band gap, and broadness of the emission) of the TL crystal/electrospun mat composites were also studied. TL and PL emission maxima of the PU-based composite mat show identical behavior due to the chemical affinity between the two structures and the smallest fiber diameter. Moreover, the PU fiber mats exhibit long-lived bluish-green emission persisting over a large number of drops.

Metal exchange in lithiocuprates: Implications for our understanding of structure and reactivity

New reagents have been sought for directed ortho cupration in which the use of cyanide reagents is eliminated. CuOCN reacts with excess TMPLi (TMP = 2,2,6,6-tetramethylpiperidide) in the presence of limited donor solvent to give crystals that are best represented as (TMP)2Cu0.1Li0.9(OCN)Li2(THF) 8, whereby both Lipshutz-type lithiocuprate (TMP)2Cu(OCN)Li2(THF) 8a and trinuclear (TMP)2(OCN)Li3(THF) 8b are expressed. Treatment of a hydrocarbon solution of TMP2CuLi 9a with LiOCN and THF gives pure 8a. Meanwhile, formation of 8b is systematized by reacting (TMPH2)OCN 10 with TMPH and nBuLi to give (TMP)2(OCN)Li3(THF)211. Important to the attribution of lower/higher order bonding in lithiocuprate chemistry is the observation that in crystalline 8, amide-bridging Cu and Li demonstrate clear preferences for di- and tricoordination, respectively. A large excess of Lewis base gives an 8-membered metallacycle that retains metal disorder and analyses as (TMP)2Cu1.35Li0.659 in the solid state. NMR spectroscopy identifies 9 as a mixture of (TMP)2CuLi 9a and other copper-rich species. Crystals from which the structure of 8 was obtained dissolve to yield evidence for 8b coexisting in solution with in situ-generated 9a, 11 and a kinetic variant on 9a (i-9a), that is best viewed as an agglomerate of TMPLi and TMPCu. Moving to the use of DALi (DA = diisopropylamide), (DA)2Cu0.09Li0.91(Br)Li2(TMEDA)212 (TMEDA = N,N,N?,N?-tetremethylethylenediamine) is isolated, wherein (DA)2Cu(Br)Li2(TMEDA)212a exhibits lower-order Cu coordination. The preparation of (DA)2Li(Br)Li2(TMEDA)212b was systematized using (DAH2)Br, DAH and nBuLi. Lastly, metal disorder is avoided in the 2:1 lithium amide:Lipshutz-type monomer adduct (DA)4Cu(OCN)Li4(TMEDA)213.

Copper(I) complexes of 8-(diphenylphosphanyl-oxy)-quinoline: Photophysics, structures and reactivity

Copper(I) complexes are studied for various potential applications due to their luminescence properties. However, issues have been identified regarding the stability of heteroleptic compounds. As a novel strategy, we propose to modify existing copper(I) complexes by introduction of molecular bridges between the different ligands. We report the synthesis and chemical properties of the complexes of 8-(diphenylphosphanyl-oxy)quinoline (POQ), a combination of a phosphine and a N-heterocycle with CuX (X = Cl, Br, I and SCN). The photophysical properties of the materials were studied. However, all four compounds were found to be labile in solution upon contact with trace amounts of water. Two POQ complexes and the decomposition products were identified as tetraphenyldiphosphoxane complexes with single crystal X-ray diffraction. We propose a design rule to prevent this behavior in future development steps.

Sandmeyer-Type Trifluoromethylthiolation and Trifluoromethylselenolation of (Hetero)Aromatic Amines Catalyzed by Copper

Aromatic and heteroaromatic diazonium salts were efficiently converted into the corresponding trifluoromethylthio- or selenoethers by reaction with Me4NSCF3 or Me4NSeCF3, respectively, in the presence of catalytic amounts of copper thiocyanate. These Sandmeyer-type reactions proceed within one hour at room temperature, are applicable to a wide range of functionalized molecules, and can optionally be combined with the diazotizations into one-pot protocols.
