摘要：
The chaotic dynamics of fractional order systems have attracted much attentions recently. In this Letter, we study the synchronization of the fractional order chaotic systems with a unidirectional linear error feedback coupling. The numerical results show that the fractional order chaotic systems can also be synchronized. (C) 2006 Elsevier B.V. All rights reserved.
摘要：
A one-dimensional chain coordination polymer [Co(II)(C_6H_5CH=CHCOOH)_2(4,4′- bipy)(H_2O)_5]n has been synthesized with cinnamylic acid, 4,4′-bipy and cobaltous chloride as raw materials. Crystal data for this complex: monoclinic, space group P21/c, a = 1.1481(3), b = 1.1230(2), c = 1.1759(3) nm, β = 97.054(4)o, V = 1.5046(6) nm~3, Mr= 617.50, Dc = 1.363 g/cm~3, Z = 2, μ(MoKα) = 0.627 mm~(-1), F(000) = 646, S = 1.062, R 0.0443 and wR = 0.1178. The crystal structure shows that two neighboring cobalt(II) ions are linked together by one 4,4′-bipy, and the whole complex molecule adopts a one-dimensional chain structure. Each cobalt(II) ion is coordinated with two nitrogen atoms from two 4,4′-bipy molecules and four oxygen atoms from four water molecules, giving a distorted octahedral coordination geometry. The electrochemical properties were analyzed by combining with the crystal structure.

The title complex (C_(26)H_(24)CuN_2O_5, Mr = 508.01) has been synthesized by o-methylbenzoic acid, 2,2'-bipyridine (bipy) and copper perchlorate in the mixed solvent of water and methanol. It crystallizes in orthorhombic, space group P2_12_12_1 with a = 0.70814(10), b = 1.6953(3),c = 1.9539(3) nm, V= 2.3457(6) nm~3, Dc= 1.439 g/cm~3, Z= 4,μ = 0.971 mm~(-1), F(000) = 1052, R= 0.0432 and wR = 0.0860. The structural determination shows that the copper atom is coordinated by three oxygen atoms from two o-methylbenzoic acids and one water molecule together with two nitrogen atoms from 2,2'-bipyridine, giving a distorted square-pyramidal coordination geometry.The cyclic voltammetric behavior of the complex is also discussed.
摘要：
Based on hydrophobic and electrostatic interactions, a norfloxacin (NOF) imprinted polymer (PI) was prepared by the combined use of bismethacryloyl-beta-cyclodextrin (BMA-beta-CD) and 2-(diethylamino)ethylmethacrylate (DEAEM) as functional monomers. Compared with the molecularly imprinted polymers (MIPs) using only BMA-P-CD or DEAEM as a functional monomer, P-2 and P-3, respectively, P, showed higher binding affinity and specificity for NOF in aqueous media. Scatchard plot analysis revealed that two classes of binding sites were formed in the imprinted polymer with dissociation constants of 0.32 mu mol/ml and 1.19 mu mol/ml, respectively. It demonstrated that the combination of hydrophobic effect and electrostatic interaction in molecular imprinting was essential for the improvement of the selective ability of the imprinted polymer. Factors that influenced rebinding of the imprinted polymer including pH, water content in the adsorbed solution were explored. (C) 2007 Elsevier B.V. All rights reserved.

摘要：
A manganese coordination polymer [Mn(3,5-Me2PhCO2)(2)(phen)](n)(phen=1,10-phenanthroline) has been synthesized by hydrothermal methods. The crystal structure was determined by single-crystal X-ray diffraction.

In the crystal the manganese atom is six-coordinated by two nitrogen atoms from phen and four oxygen atoms from four 3,5-dimethylbenzolate molecules, completing an octahedral geometry. And the title complex forms one-dimensional chain structure through bridging 3,5-dimethylbenzolate molecules.

A one-dimensional chain-like coordination polymer [Mn(phen)(2,4,6-TMBA)(2)(H2O)](n) has been synthesized from 2,4,6-tlimethylbenzoic acid, 1,10-phenanthroline and anhydrous manganese(II) sulfate and then characterized. Crystal data for this complex: tetragonal, space group 141, a = 2.05643(16), b = 2.05643(16), c = 1.3939(2) nm, V = 5.8946(11) nm, M-r = 579.54, Z = 8, D-c = 1.306 g/cm(3), mu(MoK alpha) = 0.490 mm(-1), F(000) = 2424, S = 0.985, the final R = 0.0411 and wR = 0.0950. The Flack factor is -0.01(2). The crystal structure shows that two neighboring manganese(II) ions are linked together by one bridge-chelating 2,4,6-trimethylbenzoic group, forming a one-dimensional chain structure. The manganese( II) ion is coordinated with two nitrogen atoms of one 1,10-phenanthroline, three oxygen atoms from three 2,4,6-trimethylbenzoic acids and one water oxygen atom, giving a distorted octahedral coordination geometry. The cyclic voltametric behavior of the complex was also investigated.
