Using 1,1?-bis(isoquinoline)-1,4-phenyldimethylenyl(BIQPM2+) cation as template, a new tetrameric(Bi4 I16)4-iodobismuthate-containing hybrid with formula of(BIQPM)2(Bi4 I16)·H2 O(1), has been prepared under solvothermal conditions. The centrosymmetric Bi4-4 I16 tetraanion is constructed from four edge-shared slightly distorted BiI6 octahedrons. Due to the presence of larger conjugated system(isoquinoline ring), strong π···π stacking interactions can be observed. Besides, strong I···I interactions can be monitored and extends the 0-D Bi4 I4-16 cluster to a quasi-1-D chain. The smaller energy gap of 2.13 eV is led by these non-covalent interactions. Its infrared emission might be caused by strong charge transfer between anions and cations. Furthermore, the reversible thermochromic behavior with low chromotropic temperature of 80 ℃ can be observed, whose mechanism was discussed.

The copper（Ⅱ） DPP adduct Cu（DPP）（DMF）2（H2O）-（ClO4）2 1 （DPP = 4,7-diphenyl-1, 10-phentheanthroline, DMF = N,N＇-dimethyl formamide） has been prepared by a direct synthetic method and structurally characterized. It presents a mononuclear structure and crystallizes in triclinic, space group P1 with a = 9.8717（2）, b = 12.579, c = 14.7574（2） A, α = 67.976（6）,β = 82.031（9）, γ = 80.343（9）°, V = 1668.96（9）A, Z = 1, Dc= 1.495 g/cm^3,/t（MoKα） = 0.877 mm^-1, F（000） = 774, C60H64Cl4Cu2N8O221 Mr = 1502.09, the final R1= 0.0643 and wR2 = 0.1799 for 6153 observed reflections with 1 〉 2σ（1）. Structure analysis shows that copper atom presents an unusual fivecoordination of square pyramid geometry. The whole structure is stabilized by π-π stacking interactions and static attractive forces from [ClO4]-anions. Based on crystal data, quantum chemistry calculation on DFF/B3LPY level was used to reveal the electronic structure of 1.

A novel bifunctional glycolipid which carded a cluster of thiogalactosides as the hepatocyte targeting ligand for gene delivery was prepared. Hexa-antennary alcohol 1 was used as the core scaffold to attach a cholesterol molecule by a poly（ethylene glycol） chain, while its remaining branches were linked with five acetylgalactosides, which would be deacetylated later to produce pentaantennary galactoside. Liposome containing the galactoside showed high affinity and transfection activity in hepatoma cells HepG2.

A novel coordination polymer {[Cu（en）2][Ag2I4]}, （en = ethylenediamine） was synthesized by the reaction of NaAgI2 and Cu（en）2（NO3）2·2H2O at room temperature with pH = 6.0, and the structure was characterized by X-ray single-crystal diffraction. It crystallizes in monoclinic, space group C2/m, with a=10.646（2）, b = 13.304（3）, c = 6.8445（14） ,A°, β = 118.95（3）°, C4H16N4CuAg2I4, Mr = 907.10, V= 848.3（4） A°^3, Z= 2, Dc = 3.551 g/cm^3, F（000） = 806, μ（MoKa） = 10.787 mm^-1, the final R1 = 0.0256 and wR2 = 0.0654 for 900 observed reflections with I 〉 2σ（I）. According to structural analysis, the title compound consists of template cation [Cu（en）2]^2＋ and inorganic chain [Ag2I4]n^2-. The polymeric negative chain [Ag2I4]n^2- is built up from pairs of AgI4 tetrahedron by sharing one edge. Through N-H…I hydrogen-bonding interactions, the whole structure represents a quasi-two dimensional arrangement. Electrostatic attraction exists between organic cations and inorganic chains, leading to a so-called organic-inorganic hybrid structure.

Structure analysis indicates that the platinum atom almost has the ideal octahedral coordination geometry of PtCl6. The quaternary phosphate cations （Ph3PEt^＋） acting as counter ions are in combination with PtCl6 anions by static attracting forces and H-bonds. Upon the hydrogen bonds existing between cations and anions, the whole structure represents a chain-like construction. Based on the crystal data, quantum chemistry calculation at the DFT/B3LPY level was carded out to reveal the electronic structure of 1.

为明确搅拌筛板萃取塔的操作性能,在塔内进行了液滴直径实验,平均液滴直径数据利用照相法获取,考察了搅拌转速、两相流速、体系物性、溶质传递等因素对液滴直径的影响。结果表明,增大搅拌转速会减小液滴直径,增大两相流速则会增大液滴直径,高界面张力或高黏度体系形成的液滴直径较大,高密度差体系形成的液滴直径则较小。此外,由于有机溶质的存在可降低界面张力,当两相流速改变时,塔内溶质浓度发生改变,因而体系界面张力也发生改变,进一步导致液滴直径发生改变。将实验数据进行了数学关联,关联式的计算值与实验值的平均偏差为5.6%,可为工程设计提供参考。
