Two new supramolecular compounds, [(H 4aobtc) 0.5(H 2O) 0.5] (1) and [(H 3aobtc) (H 2bipy) 0.5] (2) (H 4aobtc = azoxybenzene-3,3',4,4'- tetracarboxylic acid), were synthesized and characterized. Compound 1 has a complicated three-dimensional hydrogen bonding network with 4-connected {3 3.6 2.7} topology. Compound 2 also shows a three-dimensional supramolecular motif with hexagonal topology. The result indicated that hydrogen bonding interactions from different molecular synthons take important roles in the formation of supramolecular architectures.

Two new interpenetrating CuII/NiII coordination polymers, based on a unsymmetrical bifunctional N/O-tectonic 3-(pyrid-4′-yl)-5-(4″-carbonylphenyl)-1,2,4-triazolyl (H2pycz), {[Cu-(Hpycz)2]·2H2O}n (1) and {[Ni(Hpycz)2]·H2O}n (2), have been solvothermally synthesized and structure characterization. Single crystal X-ray analysis indicates that compound 1 shows 2-fold parallel interpenetrated 44-sql layers with the same handedness. The overall structure of 1 is achiral - in each layer of doubly interpenetrating nets, the two individual nets have the opposite handedness to the corresponding nets in the adjoining layers - while 2 features a rare 8-fold interpenetrating 66-dia network that belongs to class IIIa interpenetration. In addition, compounds 1 and 2 both show similar paramagnetic characteristic properties. Crown Copyright © 2014 Published by Elsevier Inc. All rights reserved.

On the basis of a temperature-induced effect, the solvothermal reaction of Co(Ac)2·4H2O, 5-amino-2,4,6-triiodoisophthalic acid (H2atibdc), and 1,4-bis(2-methyl-imidazol-1-yl)butane (bib) at 80 °C gave a new coordination polymer [Co(bib)(atibdc)] (1), which shows a two-dimensional (2D) network with left- and right-handed helical chains. By raising the reaction temperature to 130 °C, a pair of homochiral enantiomers [Co(bib)(atibdc)]·2H2O (2, 2M, and 2P) were successfully obtained, displaying a three-dimensional (3D) framework with three kinds of unique helical chains. Keeping the temperature of the reaction system to 150 °C, excited, an in situ iodine elimination reaction occurred, and a new linker 5-aminoisophthalic acid (H2aipa) was generated, which then cooperated with the bib ligand to construct a coordination polymer [Co(bib)(aipa)] (3), showing a 3D 3-fold interpenetrating architecture. The comparison of final solid structures exhibits an exclusive temperature-induced effect on the construction of the coordination polymer. Furthermore, via a single-crystal-to-single-crystal (SCSC) transformation, the 2D network of 1 can be derived from the 3D framework of 2, which presents a rare type of temperature-solvent induced SCSC transformation. In addition, the magnetic properties of 1-3 have been investigated as well. © 2016 American Chemical Society.

Two novel entangled coordination polymers, [Zn(abda)(bimh)]n (1) and [Cd(dtba)(bimh)]n (2) (H2abda = azobenzene-4, 4′-dicarboxylic acid, H2dtba = 2,2′-dithiobisbenzoic acid, bimh = 1,6-bis(2-methylimidazole-1-yl)hexane), have been synthesized using long mixed ligands. Complex 1 features rare 2D parallel interpenetrated 4 4-sql networks which show the same handedness. Interestingly, in the interpenetrating nets, A-chains [Zn(bimh)]n of one layer co-use the helical shaft with B-chains [Zn(abda)]n of the other layer of double-layers. Complex 2 shows a unique 3D 3-fold interpenetrating homochiral 86 network, and each single net is constructed from right-handed [Cd(dtba)]n single helices and left-handed [Cd(bimh)]n double-stranded helices.

Two coordination polymers (CPs), {[Zn2(BMB)(5-AIPA) 2]·2H2O}n(1) and [Zn(BMB)(5-NIPA)] n(2) {BMB = 1, 4-bis[(2-methyl-imidazol-1-yl)methyl]benzene, 5-AIPA = 5-aminoisophthalic acid, 5-NIPA = 5-nitroisophthalic acid}, were synthesized under hydrothermal conditions. Compound 1 displays a 2D double-layer structure, which is packed into a 3D supramolecule by interlayer hydrogen bonds and π-π stacking interactions. Compound 2 displays a threefold interpenetrating 3D network, which is composed of left-handed helical chains and two types of meso-helical chains along different directions.

On the basis of 1,4-bis(2-methyl-imidazol-1-yl)butane (bib), four new coordination polymers (CPs), namely, {[Zn(bib)(male)]2·2H 2O}n (1), {[Zn(bib)(suc)]·H2O} n (2), {[Zn(bib)(fum)]·CH3OH}n (3), {[Zn(bib)(bpdc)]·2H2O}n (4) (H2mal = maleic acid, H2suc = succinic acid, H2fum = fumaric acid, bpdc2- - = 2,2'2′-bipyridine- 3,3'3′- dicarboxylate) have been synthesized by the reaction of zinc(II) salts and bib with four different aliphatic/aromatic binary acids under the same conditions, respectively. These coordination polymers are structurally characterized by elemental analysis, IR, single-crystal X-ray crystallography and TG analysis. All of them host a same meso-helical chain constructed by metal centers and bib ligands. 1 and 2 feature similar 2-D wave-like topology containing a meso-helical chain; 3 is a 3-D diamond-like structure, comprising two different meso-helical chains, and shows 4-fold interpenetrated framework with {6-6} topology; 4 is a 3-D diamond-like structure, containing a meso-helical chain, and displays 3-fold interpenetrated net with {6-6} topology. In addition, the phase purities of bulk samples were further identified by X-ray powder diffraction analysis. Solid state luminescent spectra have been investigated at room temperature, and the luminescent lifetime of 3 was monitored at room temperature. © 2013 Published by Elsevier B.V.

The formation of the obesity has a close relationship with appetite. People’s appetite usually influences by two regulation systems: appetite regulation system and cognitive regulation system. Appetite regulation system plays a significant role in ingestion and energy balance. It can be divided into two groups: promoting appetite which includes MCH, Gremlin, GHSP, Gal, and so on; Restraining appetite which includes PYY, CCK, CART, α -MCH. They make up the appetite regulation network and adjust the balance of energy and obesity. If one of the chains broken, it will cause greediness or anorexia, which results in obesity or losing weight. Also, lacking the self-understanding is a reason for the obesity. © 2015 Taylor & Francis Group, London.

Five new solvent-induced cadmium coordination architectures, {[Cd(bib)(5-Br-H2ip)]·EtOH}n (1), {[Cd0.5(bib)0.5(5-Br-H2ip)0.5]·3H2O}n (2), {[Cd2(bib)(5-Br-H2ip)2(MeOH)]}n (3), {[Cd(bib)0.5(5-Br-H2ip)(H2O)2]·H2O}n (4), and {[Cd(bib)0.5(5-Br-H2ip)(H2O)]}n (5), have been constructed from the same materials (1,4-bis(2-methyl-imidazol-1-yl)butane (bib), 5-bromoisophthalic acid (5-Br-H2ip) and Cd(Ac)2·2H2O) under different reaction solvents. As controlled by solvent systems, compound 1 shows a 3-fold interpenetrating 3D framework based on the left- and right-handed helical chains, while compound 2 reveals a 3-fold interpenetrating 3D network and each single net is based on the left-handed, right-handed and meso-helical chains. Compound 3 is a 3D framework that can be simplified as a 6-connected net with (48·62) topology. Both 4 and 5 display 3D supramolecular frameworks through weak aromatic π-π stacking interactions and hydrogen bonding interactions. However, the topologies of 4 and 5 are definitely different. Compound 4 presents a 3-connected net with (82·10) topology, while compound 5 reveals a 4-connected net with (42·63·8) topology. The effects of solvents on the crystal structures were discussed and thermogravimetric analysis and solid-state photoluminescence results for 1-5 were investigated.

Two new three-dimensional (3D) porous structures based on the mixed flexible and rigid organic ligands, [Cd1.5(bmip)(tpa) 1.5(DMF)1.5]n (1) and [Co1.5(bmip) 0.5(bpdc)1.5(DMF)2]n (2) (bmip = 1,3-bis(2-methylimidazolyl)propane, H2tpa = terephthalic acid, H 2bpdc = biphenyl-4,4′-dicarboxylic acid, DMF = N,N-dimethylformamide) have been prepared under solvothermal conditions. Complex 1 contains a trinuclear Cd unit, in which the trinuclear Cd cluster acts as an eight-connected node with two pairs of flexible bmip and six rigid tpa ligands. Complex 2 exhibits a two-fold interpenetrated porous network based on a trinuclear Co cluster as eight-connected vertices with two flexible bmip and six rigid tpa ligands. Both 1 and 2 show selective gas adsorption of CO2 over N2 and H2. Furthermore, complex 1 displays an uncommon CO2 adsorption isotherm and hysteretic desorption behaviors at 195 K. © the Partner Organisations 2014.
