“…Mass spectra were obtained on a JEOL SX-102A instrument operating in electron impact (EI) mode. The thermogravimetric analyses (TGA) were recorded on a Seiko TG/DTA 300 instrument under an atmospheric pressure of N 2 with a flow rate of 100 cm 3 min 21 and with a heating rate of 10 uC min 21 . Elemental analyses were carried out at the NSC Regional Instrumentation Center at National Cheng Kung University, Tainan, Taiwan.…”

“…In agreement with this proposition, N-H … O hydrogen bonding has been observed as a key driving force for constraining an analogous aminoalkoxide fragment (L) into a fixed conformation, giving rise to a 10-membered metal wheel compound of formula [Cu II Cl(L)] 10 [L ~OC(CF 3 ) 2 CH 2 NHCH 2 CH 2 NMe 2 ]. 21 Other physical constants relevant to the CVD experiments are listed in Table 4. It appears that complex 1 shows the lowest melting point (87-88 uC) among all the copper complexes.…”

“…Planar, high-nuclearity M–O based complexes have attracted increasing attention due to their fascinating properties. − Each metal center in the planar core tends to generate two perpendicular open sites, which could be conjugated into two metal-active surfaces used to enhance the related properties of the planar complexes. With consideration of the complementarity and structural advantages, the material-integrated planar high-nuclearity node into MOFs could generate unprecedented separation performances, such as metal-active surfaces within pores that exert strong binding interactions with specific guest molecules.…”

One of the emerging problems plaguing the chemical industry today is the efficient and costeffective separation of C 2 hydrocarbons. In order to help address this problem, we report a new material, NbU-1, constructed by extremely cheap starting materials. The special structural characteristics of NbU-1 such as the planar, mixed-valence copper clusters and Lewis-basic adsorption channels enforce interactions with acetylene molecules that lead to the highest kinetic separation efficiency for C 2 H 2 /C 2 H 4 . Via DFT-D calculations, it is indicated that C 2 H 2 molecules are adsorbed onto the two adjacent Cu(I) centers, but not the usual single open metal sites of Cu centers. The reported results not only provide information for a deep investigation into the separation mechanism but also offer an alternative strategy for preparing cost-effective materials that can perform highly efficient separations of light hydrocarbons.

“…All reactions were performed under an inert atmosphere using anhydrous solvents or solvents treated with appropriate drying reagent. The CF 3 substituted amino alcohol ligands of formulas HOC(CF 3 ) 2 CH 2 NMe 2 and HOC(CF 3 ) 2 CH 2 NHR, R = Me, CH 2 CH 2 OMe, and Bu t , were prepared according to the literature method, while the tridentate ketoimine ligand OC(CF 3 )CH 2 C(CF 3 )NCH 2 CH 2 NMe 2 was obtained from a reaction of hexafluoroacetylacetone with N , N -dimethyl-ethylenediamine in the presence of montmorillonite K10 …”

The syntheses of two distinctive types of indium complex derived from trimethylindium (InMe(3)) are reported. The first kind has a generalized structural formula [InMe(2)(amak)](2), where (amak)H is an abbreviation for a series of chelating amino alcohol ligands HOC(CF(3))(2)CH(2)NHR, R = (CH(2))(2)OMe (1), Me (2), and Bu(t) (3), as well as HOC(CF(3))(2)CH(2)NMe(2) (4); while the second type of complex is illustrated by [InMe(2)(keim)] (5), for which (keim)H is a tridentate ketoimine ligand of structural formula O=C(CF(3))CH(2)C(CF(3))=NCH(2)CH(2)NMe(2). The solid-state structures of 2 and 5 were determined using single crystal X-ray diffraction studies. For the aminoalkoxide complexes 2-4, the existence of dimeric In(2)O(2) core structures in the solid state has been established with the amino fragment located trans to the alkoxide ligands, in a molecular arrangement which is in contrast to the distorted, trigonal bipyramidal geometry observed for the ketoiminate complex 5. Moreover, VT NMR studies of 2 revealed a rapid dimer-to-monomer equilibration and simultaneous rupture of the N-->In dative interaction, affording two interconvertible isomers related by having the N-Me substituents in either trans or cis dispositions. For complexes 2 and 5, deposition of In(2)O(3) thin films was successfully conducted at temperatures 400-500 degrees C, using O(2) as the carrier gas to induce indium oxide deposition and to suppress carbon impurity present in the thin film. Scanning electron micrographs (SEMs) revealed the surface morphologies. The atomic composition of these films was examined by both X-ray photoelectron spectroscopy (XPS) and Rutherford backscattering (RBS) methods, while X-ray diffraction studies (XRD) confirmed the formation of a preferred orientation along the (222) planes.
