AbstractTwo novel 25,27‐dihydroxy‐26,28‐bis(3‐phenyilhiapropoxy)‐calix[4]arene (3) and 25,27‐dihydroxy‐26,28‐bis(3‐phenylthiapropoxy)‐5,11, 17, 23‐tetra‐tert‐butylcalix[4]arene (4) were synthesized for the evaluation of their ion‐selectivity in ion‐selective electrodes (ISEs). ISEs based on 3 and 4 as neutral ionophores were prepared, and their selectivity coefficients for Ag+ (lg Apotag,M) were investigated against other alkali metal, alkaline‐earth metal, aluminum, thallium (I), lead and some transition metal ions using the separate solution method (SSM). These ISEs showed excellent Ag+ selectivity over most of the interfering cations examined, except for Hg2+ and Fe2+ having relative smaller interference (Ig Kpotag,M≤ − 2.1).

Authors: Yin Han‐Dong , Wang Chuan‐Hua , Ma Chun‐Lin , Wang Yong 
Published: September 2010

AbstractTriphenyltin thiazole‐2‐carboxylate (1) and triphenyltin 3‐pyridinylcarboxylate (2) were synthesized by the reaction of sodium thiazole‐2‐carboxylate or sodium 3‐pyridinylcarboxylate with the triphenyltin chloride and their crystal structures were determined by single crystal X‐ray diffraction analysis. In the structure of 1, the tin atom is five‐coordinated in a distorted trigonal bipyramidal structure. Due to the presence of a close intermolecular Sn…S interaction distance of 0.3666 nm, the structure can be described as a weakly‐bridged one‐dimensional chain compound. In the structure of 2, the tin atom is five‐coordinated with bridging 3‐pyridinylcarboxylate ligands N atom and resulting structure is one‐dimensional chain compound.

AbstractCrystal structure of the title compound, [Ni(Im)6] (NO3)2·4H2O (Im = imidazole), was determined by X‐ray crystallographic analysis. The crystal structure consists of discrete Ni(Im)26+ cation, NO−3 anion and four uncoordinated water molecules. It crystallizes in the hexagonal system, space group P63, with lattice parameters a = b = 0.9003(2) nm, c = 2.1034(4) nm, and Z = 2. The Ni(II) ion is centro‐ symmetric octahedron geometry with the NiN6 core. Six imidazole molecules are coordinated to each nickel (II) atom through its tertiary nitrogen atom. The short and long bond distances of Ni‐N are 0.2059(6) and 0.2204(7) nm, respectively. In the solid state, [Ni(Im)6]2+, H2O moieties and nitrate anions form the three dimensional hydrogen bonds network which stabitizes the crystal structure.

Authors: Song Li‐Ping , Zhu Shi‐Zheng , Huang Ji‐Ling 
Published: September 2010

AbstractOxidation of aldehyde 4‐chloro‐2, 3,5, 6‐tetrafluorophenylhydrazones (1) with [bis(acetoxy)iodo] benzene leads to the formation of nitrile imines (2) which can react in situ with acrylonitrile to produce l‐(4‐chloro‐2,3,5,6‐tetrafluorophenyl)‐3‐substituted‐5‐cyano‐4, 5‐dihydropyrazoles (3) in moderate to good yields. The structures of new compounds were fully confirmed by their spectral data and elemental analyses. A plausible reaction mechanism for the generation of nitrile imine is proposed.
A New Type of Deaggregators, the Bolaamphiphilic DeAgrs. Observations of the Dependence of Deaggregating Ability on Aggregator Concentration and Solvent Aggregating Power
Authors: Zhou Qi‐Zhong , Shi Ji‐Liang , Jiang Xi‐Kui , Li Zhan‐Tiiig 
Published: September 2010

AbstractFour new amphiphilic molecules, i.e., the bolaamphiphiles n‐trimethylamino n‐hexadecanoate (deAgr 16), n‐dodecanoate (deAgr 12), n‐undecanoate (deAgr 11), and n‐octanoate (deAgr 8) were synthesized. Their ability as deaggregators to break up the aggregating systems of hexadecyl β‐naphthoate (A16) and dodecyl β‐naphthoate (A12) in dioxanewater binary solvent systems was investigated in a number of solvent systems and at different A16 and A12 concentrations. The results reveal that this new type of bolaamphiphilic molecules appears to be one of the most efficient deaggregators reported, which, at very low concentrations, can effectively break up the aggregating systems of highly concentrated A16 and A12. It is also found that bolaamphiphfles with longer aliphatic chains possess greater deaggregating ability. However, when the overall concentrations of A16 and A12 are very low but still above their critical aggregating concentration, these bolaamphiphilic molecules lose their deaggregating power and tend to coaggregate with the aggregated A16 or A12 molecules. The quite efficient deaggregating ability of the long‐chain bolaamphiphfles (deAgr 16 and deAgr 12), as compared to the short‐chain deAgr 8, has been ascribed to their dynamic switch‐on/switch‐off behavior involving coiled‐up and uncoiled conformations of their long aliphatic chains.

Published: September 2010

AbstractThe synthesis of phosphorylated Achyranthes bidentata polysaccharide (P‐AbPS) was reported based on different strategies. The P‐AbPS with high degree of substitution (D.S. > 0.5) was obtained when phosphorus oxychloride (POCl3) was used as a phosphorylating agent and trimethyl phosphate‐pyridine or dimethyl formamide was used as solvent. The influences of different solvents and reaction conditions were discussed. The pharmacology assay shows that P‐AbPS possesses antitumor activity against sarcoma 180 and Lewis lung cancer in mice.

Published: September 2010

AbstractThe use of tetra‐substituted ammo aluminum phthalocyanine (TAAIPc) as a new red‐region fluorescent substrate for horseradish peroxidase (HRP)‐based enzyme‐linked immunosorbent assay was investigated. TAAIPc displayed an excitation maximum at 610 nm and emission maximum at 678 nm in a strong acidic medium. In the presence of HRP, trace amounts of H2O2 could rapidly and significantly react with TAAIPc, thus quenching the fluorescence of TAAIPc. The Michaelis‐Menten parameters Km and Vmax were measured to be 2.82 × 10−6 mol/L−1 and 6.0 × 10−9 mol·L−1, respectively. In this paper, TAAIPc was used in an HRP‐based enzyme‐linked immunosorbent assay (ELISA) of α‐fetoprotein (AFP) in human serum with satisfactory results. AFP could be determined in the concentration range of 0.5–200 ng/mL with a detection limit of 0.2 ng/mL, which was close to that of radioimmunoassay. The advantage of proposed method was strongly minimizing the interference resulting from background fluorescence or scattering light and had a high analytical sensitivity.

Authors: Taher Mohammad Ali 
Published: September 2010

AbstractVanadium is quantitatively retained on 2‐(5‐bromo‐2‐pyridylazo)‐5‐diethylaminophenol (5‐Br‐PADAP)‐ammonium tetraphenylborate with microcrystalline naphthalene or by a column method in the pH range of 2.1–4.5 from a large volume of aqueous solutions of various samples. After filtration, the solid mass consisting of the vanadium complex and naphthalene was dissolved with 5 mL of dimethylformamide and the metal was determined by the third derivative spectrophotometry. Vanadium complex can alternatively be quantitatively adsorbed on ammonium tetraphenylborate‐naphthalene adsorbent packed in a column and determined similarly. About 0.05 μg of vanadium can be concentrated in a column from 250 mL of aqueous sample, where its concentration is as low as 0.2 ng/mL. The interference of a large number of anions and cations has been studied and the optimized conditions developed were utilized for the determination of trace amount of vanadium in various samples.

Authors: Hayat Benabadji Saldina , Ren Wen , Hai‐Feng Chen , Shen‐Gang Yuan 
Published: September 2010

AbstractComparative molecular field analysis (CoMFA), a three dimensional quantitative structure‐activity relationship (3D‐QSAR) method was applied to a series of diindolylmethane (DIM) analogs to study the relationship between their structure and their induction of CYP 1A1‐associated ethoxyresorufin‐O‐deethylase (EROD) activity. A DISCO model of pharmacophore was derived to guide the superposition of the compounds. The coefficient of cross‐validation (q2) and non cross‐validation (r2) for the model established by the study are 0.827 and 0.988 respectively, the value of variance ratio (F) is 103.53 and standard error estimate (SEE) is 0.044. These values indicate that the CoMFA model derived is significant and might have a good prediction for the catalytic activity of DIM compounds. As a consequence, the predicted activity values of new designed compounds were all higher than that of the reported value.

Published: September 2010

AbstractPotential energy surface of HNOS system is investigated by means of MP2 method with 6–311 ++ G(d, p) basis set. The energy for each minimum and saddle point on the potential energy surface is corrected at the QCISD(T)/6–311 ++ G(3df, 2p) level of theory with zero‐point vibrational energy included. As a result, eighteen isomers are theoretically predicted and cis‐HNSO is found to be global minimum on the potential energy surface. Wherein, fourteen isomers are considered as kinetically stable species, and should be experimentally observed. Comparisons are made for HNOS system with its analogues, HNO2 and HNS2. The nature of bonding and isomers'stability of HNOS system are similar to HNS2. The obvious similarities and discrepancies among HNOS, HNO2 and HNS2 are attributed to the hypervalent capacity of sulfur, oxygen and nitrogen atoms.

AbstractThe ternary Cu(II) complex with 2,2′‐bipyridyl (bipy) and L‐methioninate (L‐Met) has been synthesized and characterized by elemental analysis, molar conductivity, UV‐Vis spectra, IR spectra and pH‐potentiometric titration methods. The structure of the complex [Cu(L‐Met) (bipy) (H2O)]ClO4 · 3/8H2O was characterized by the X‐ray diffraction analysis. It crystallizes in the triclinic system, space group P1 with four molecules in a unit cell of dimensions, a = 0.7656(2) nm, b = 1.3142(3) nm, c = 2.0596(4) nm, α = 97.70(3)°, β = 97.96(3)°, γ = 94.33(3)°, V= 2.0244(8) nm3, R1, = 0.0441 and wR2 = 0.0678. The crystal contains four crystllographically independent [Cu(L‐Met) (bipy) (H2O)]+ complexes (Cu1—Cu4), having a distorted square‐pyramidal geometry with the same coordinated atoms around each copper center. The base plane is occupied by two nitrogen atoms of one bipy, the amino nitrogen atom and one carboxylate oxygen atom from each independent L‐Met moiety, and one water oxygen at an axial position. Cu1 and Cu3 are essentially enantiomers of Cu2 and Cu4. The four molecules are packed with each other by intermolecular hydrogen‐bonding and aromatic‐ring stacking interactions.
Resonance Rayleigh Scattering Spectra of Thorium (IV)‐bisazo Dye of Chromotropic Acid‐protein Systems and Their Analytical Applications
Authors: Fan U , Shao‐Pu Liu , Da‐Cheng Yang , Hong‐Qun Luo 
Published: September 2010

AbstractIn acidic medium, thorium (IV) can react with a bisazo dye of chromotropic adds such as arsenazo HI (AA in), arsenazo M (AA M), chlorophosphonazo III (CPA III) and chlorosulphonphenol S (CSP S) to form an anionic chelate which further interacts with some proteins to produce a complex. This results in a significant enhancement of intensity of the resonance Rayleigh scattering (RRS) and the appearance of a new RRS spectrum. There are a few obvious RRS peaks in the range of 400–470 nm and the most intensive peak of them is located at 470 nm. The intensity of RRS is directly proportional to the concentration of protein in the range of 0—l.öμg‐mL−1 for Th(IV)‐CPA III system, 0–2.8 μg‐mL−1 for Th(IV)‐AA M system, 0–2.0 μg·mL−1 for Th(IV)‐AA III system and 0–0.28 μg·mL−1 for Th(IV)‐CSP S system, respectively. The detection limits for BSA (3s̀) are 10.7 ng·mL−1 for Th (IV)‐CPA III, 6.3 ng·mL−1 for Th(IV)‐CSP S, 13.6 ng·mL−1 for Th(IV)‐AA III and 22.1 ng·mL−1 for Th(IV)‐AA M, respectively. This new RRS method has high sensitivity and fairly good selectivity and can be applied to the direct determination of proteins in human serum with satisfactory results.

Authors: Lei Ma , Li‐Zhu Wu , Li‐Ping Zhang , Chen‐Ho Tung 
Published: September 2010

AbstractPolymer microcapsule was employed as a reaction medium to achieve enantioselectivity in photochemical reduction of phenyl cyclohexyl ketone and photoelectrocyclization of tropolone methyl ether under the influence of various chiral inductors. In all cases, low but evident enantioselectivity was observed. The poor enantioselectivity is probably due to the facts that not all the capsules include simultaneously both the chiral inductor and the reactant molecules, and the wall of the microcapsule is not rigid enough to hold the reactant and the chiral inductor molecules in close contact.

AbstractThe aggregates in sodium dedecylsulphate (SDS)/dimethylbenzene/water systems have been investigated using dissipative particles dynamic (DPD) simulation method. Through analyzing three‐dimensional structures of aggregates, three simulated results are found. One is the phase separation, which is clearly observed by water density and the aggregates in the simulated cell; another is the water morphology in reverse micelle, which can be found through the isodensity slice of water including bound water, trapped water and bulky water; the third is about the water/oil interface, i. e., ionic surfactant molecules, SDS, prefer to exist in the interface between water and oil phase at the low concentration.
Isomerization Mechanisms of C5H2 on the Triplet and Singlet Potential Energy Surfaces
Authors: Cong‐Jie Zhang , Li‐Ling Zhang , Ze‐Xing Cao , Qian‐Er Zhang 
Published: September 2010

AbstractDensity functional theory calculations with the B3LYP functional are used to study the structure and stabilities of C5H2 isomers and possible isomerization mechanisms on the triplet and singlet potential energy surfaces. Calculated results show that isomerization of C5H2 is likely to occur on the triplet potential energy surface while direct conversions of the singlet C5H2 isomers via 1,3‐hydrogen migration transition states are extremely difficult dynamically. In such isomerization processes, the hydrogen transfer processes in carbon chains are the rate‐determining steps. The triplet species except the linear ground state X3 Σ are rather less stable than their singlet forms, although the singlet and triplet species have similar geometries.
Theoretical Study on the Structures and Stability of Isomers and Complex of [Si, C, O, O] System
Authors: Hai‐Tao‐C Yu , Bo Li , Yu‐Juan Chi , Hong‐Gang Fu , Ze‐Sheng Li , Jia‐Zhong Sun 
Published: September 2010

AbstractA detailed singlet potential energy surface (PES) of [Si, C, O, O] system including a van der Waals (vdW) complex SiO CO, eight isomers, and twelve transition states is investigated by MP2 and QCISD(T) (single‐point) methods. At the final QCISD(T)/6–311 + G(2df)//MP2/6–311G(d) level with zero‐point energy included, the complex SiO‐CO is found to be thermodynamically and kinetically the most stable species. Although eight isomers are located as local energy minima, they are rather unstable toward isomerization to the dissociation fragments or complex. For the reaction of silicon atoms with carbon dioxide, two competitive reaction channels are found, and the primary pathway, which leads to the products of SiO and CO fragments, is the direct oxygen‐abstraction process from carbon dioxide by silicon atom with a 41.16 kJ/mol reaction barrier height. Our predications are in good agreement with previous experimental and theoretical studies.

AbstractThe pyruvic add‐salicylhydrazone and its new complex of Pr(III) were synthesized. The formulae C10H10N2O4(mark as H3L) and [Pr2(L)2(H2O)2]·3H2O (L= the triad form of the pyruvic acid‐salicylhydrazone [C10H7N2O4]3‐) were determined by elemental and EDTA volumetric analysis. Molar conductance, IR, UV, X‐ray and1H NMR were carried out for the characterizations of the complex and the ligand. The thermal decompositions of the ligand and the complex with the kinetic study were carried out by non‐isothermal thermogravimetry. The Kissinger's method and Ozawa's method are used to calculate the activation energy value of the main step decomposition. The stages of the decompositions were identified by TG‐DTG‐DSC curve. The non‐isothermal kinetic data were analyzed by means of integral and differential methods. The possible reaction mechanism and the kinetic equation were investigated by comparing the kinetic parameters.
