Synthesis, Crystal Structure and Reducibility of K2NiF4 Type Oxides Sm2‐xSrxCuO4
Authors: Zhu Ying‐Hong , Lou Hui , Liu Jia‐Geng , Liu Xue‐Jian , Ma Fu‐Tai 
Published: September 2010

AbstractK2NiF4 type compounds Sm2‐xSrxCuO4(0 ≤ x ≤ 1.2) were prepared. Rietveld refinement of powder diffraction data snows that the crystal system of these compounds belongs to T type tetragonal structure of space group I4/mmm, and the addition of Sr causes a dramatic shift of the O(I) ions along the c axis from Sm (Sr) toward Cu while scarcely affecting the Cu—O (II) bond in basal CuO4 plane. From XRD data, it can be seen that when 0.0 ≤ x ≤ 0.6, Sm2‐xSrxCuO4 belongs to a single‐phase K2NiF4 type structure, while at x ⩾ 0.7, both the free SrO phase and the CuO phase exist in these compounds. From the results of XPS and Rietveld refinement, it can be seen that after replacing Sm3+ with Sr2+ of lower valence, the valence of Cu and Sm does not change apparently, and thus some defect must be formed at the oxygen ion positions and/or position A on A2BO4 to keep charge balance and to stabilize the structure.
Characters of the Plateau of Methanol Increment in Frontal Analysis in Reversed Phase Liquid Chromatography
Authors: Geng Xin‐Du , Regnier Fred E. 
Published: September 2010

AbstractWith insulin methanol‐water, and the ion‐pairing agent, hydrochloric acid and trifluroacetic acid (TFA), the character of the first plateau (FP) on the elution curve of frontal analysis in reversed phase liquid chromatography (RPLC) was investigated by on‐line UV‐spectrometry and identified with nuclear magnetic resonance (NMR) spectrometry and mass spectrometry. The profile of the FP is the same as that of a usual elution curve of methanol in frontal analysis (FA). When the insulin concentration was limited to a certain range, the height of the FP was found to be proportional to the insulin concentration in mobile phase and its length companying to shorten. The FP profile on the intersection of two tangents reflects the components of the microstructure in the depth direction of the bonded stationary phase layer and the desorption dynamics of the displaced components. The displaced methanol was quantitatively determined by NMR and on‐line UV spectrometries.TFA with high UV absorbance can not be used as an ion‐pairing agent for the investigation of the FP in RPLC, but it can be used as a good marker to investigate the complicated transfer process of components in the stationary phase in RPLC. A stoichiometric displacement process between solute and solvent was proved to be valid in both usual and FA in RPLC. From the point of view of dynamics of mass transfer, the solutes can only contact to the surface of stationary phase in usual RPLC, while solute can penetrate into it in FA of RPLC. The solvation of insulin in methanol and water solution as an example indicating the usage of the FP in the FA was also investigated in this paper.
ESR Studies on the Micellization Behaviors of a Series of Novel Asymmetric Gemini Surfactants
Authors: Wu Yi‐Tihan , Wang Jin‐Ben , Liu Ming‐Hua , Liang Wen‐Ping 
Published: September 2010

AbstractThe synthesis of a new series of asymmetric cationic gemini surfactant and the investigation of their micellization behaviors by electronic spin resonance (ESR) as well as the surface tension measurements were reported. 4‐Oxo‐2,2,6,6‐tetramethylpiperidine‐N‐oxyl (4‐oxo‐TEMPO) is used as the spin probe. The surfactants studied have the general formula [CnH2n+1 N+ (CH3)2C6H12N+(CH3)2CmH2m+1]Br2−, referred to as dimeric n‐6‐m surfactants, in which n and m are the numbers of carbon atoms in the asymmetric side alkyl chains. From the experimental data, rotational correlation time τc, surface tension and critical micelle concentration (cmc) values, the physical properties of these new surfactants have preliminarily been e‐valuated. It is shown that this new series of asymmetric gemini surfactants has interesting micellization behaviors, and they are very different in aggregating tendency from their asymmetric analogues.
Acidichromism in the Mixed Langmuir‐Blodgett Films of Stearic Acid with a Carbazole‐containing Schiff Base
Authors: Liu Yao‐Hu , Liu Ming‐Hua 
Published: September 2010

AbstractA new Schiff base containing carbazole group (CzSB) was synthesized. Although the compound can not form stable monolayer at air/water interface itself, it does form stable monolayers by mixing with stearic acids as verified from the surface pressure‐area measurements. The mixed monolayers can be deposited by vertical dipping method. UV Spectroscopic studies of the mixed LB films reveal a broadening and red shift of the absorption spectra compared to those of CzSB in the ethanol solution, which confirms the formation of organized aggregates of the compounds in the mixed LB films. An ordered LB film was obtained as confirmed by using low‐angle X‐ray diffraction. The mixed LB film shows acidichromism, that is, the colors of the LB films can be reversibly changed upon exposing to HCl and NH3 gas alternatively. On the basis of FT‐IR measurement, it is proposed that the protonation of the imine group in the compound is the reason for the acidichromism.

Published: September 2010

AbstractA new magnesium borate MgO·B2O3·4H2O was synthesized by the method of phase transformation of double salt and characterized by XRD, IR spectra and TG. The structural formula of this compound was Mg·[B2O(OH)6]·H2O. The enthalpy of solution of MgO·B2O3·4H2O in HCl (1.0492 mol·L−1) was determined. With the incorporation of the standard molar enthalpies of formation of MgO (s), H3BO3(s), and H2O (1), the standard molar enthalpy of formation of ‐ (3135.31 ± 1.68) kJ·mol−1 of MgO·B2O3·4B2O was obtained. Thermodynamic properties of this compound were also calculated by group contribution method.

Authors: Chuan‐Ming Jin , Guo‐Yuan Lu , Xiao‐Zeng You , Xun Guo , Min‐Zbi Gui , Hong Zhang 
Published: September 2010

AbstractThep‐nitrophenylazo calix[4]arene derivatives 1a‐1d with nonlinear optical (NLO) properties were prepared by the diazo‐coupling reaction of calix[4]arene withp‐nitrophenyl diazonium. The diazotization reaction ofp‐nitroaniline was carried out with isoamyl nitrite as a source of nitrous add in EtONa/EtOH under refluxing condition. X‐Ray crystallographic analysis and1H NMR spectra reveal that they exist as cone conformation in crystal state or in solution. HRS measurements at 1064 nm in THF indicate thatp‐nitro‐phenylazo calix[4]arenes have higher hyperpolarizability βzvalues than the corresponding reference compound 4‐(4‐nitrophenylazo)‐2, 6‐dimethyl‐phenol, without red shift of the charge transfer band. The tetrakisp‐nitrophenylazo calix[4]arene (2) with longer alkyl chains can form monolayer at the air/water interface.

Published: September 2010

AbstractThe noncovalent interactions of night blue (NB) with several nucleic acids in buffer medium of Britton‐Robinson at pH 4.1 have been studied by spectroscopic methods. It is shown that the binding of NB with nucleic acids involves the J‐aggregation of NB molecules on the surface of nucleic acids. The aggregation was encouraged by polyanions nucleic acids, in which nucleic acids served for acting templates. In this connection, a new method of nucleic acids with sensitivity at nanogram level is proposed based on the measurement of enhanced resonance light scattering (RLS). The linear range of ctDNA, fsDNA and yRNA is 0.01—2.5, 0.03—2.5 and 0.04—1.0 μg/mL, respectively, and the corresponding detection limits (3s̀) are 9.4, 7.3 and 5.7 ng/mL at 2.5 × 10–5mol/L of NB. Synthetic and real samples were analyzed with satisfactory results.

AbstractTwo new dibenzyltin bisdithiocarbamates (PhCH2)2Sn(S2CNEt2)2 (1) and (PhCH2)2Sn(S2CNC4H6)2 (2) were synthesized by the reaction of dibenzyltin dichloride with dithiocarbamates and characterized by elemental analysis, IR, 1H NMR and MS spectra. The crystal structures were determined by X‐ray single crystal diffraction analysis. In both complexes, the tin atom is six‐coordinated in a distorted octahedral configuration. In the crystals of 1, the molecular packing in unit cell reveals that the two adjacent molecules are symmetrically linked to each other in dimers by two Sn … S interactions of 0.3816 nm. In the crystals of 2, the molecules are packed in the unit cell in one‐dimensional chain structure linked by weaker intermolecular S … S contacts.

Authors: Si‐Zhong Wu , Shi‐Wei Lu 
Published: September 2010

AbstractThe catalytic performance of Ni(η5‐Ind)2 complex in me dimerization of propylene was studied in combination with an organoaluminum co‐catalyst, eventually in the presence of a phosphine ligand. The effects of the type of aluminum co‐catalyst and its relative amount, the nature of phosphine ligand and P/Ni ratio as well as the reaction temperature were examined. The results indicated that the nickel precatalyst exhibited high productivity for the propylene dimerization together with organoaluminum. It was likely to strongly modify the reactivity in the catalytic system when using phosphine ligand as additives, especially at the reaction temperature below 0 °C. The catalytic system based on Ni(η5‐Ind)2 complex displayed an extremely high productivity (TOF up to 169000 h−1) and a good regioselectivity to 2,3‐dimethylbutenes (2,3‐DMB) in dimers (66.4%) under proper reaction parameters.

Published: September 2010

AbstractA flexible approach to ethyl (3R.4S)‐N‐Boc‐4‐amino‐3‐hydroxy‐S‐phenylpentanoate (N‐Boc‐AHPPA‐OEt), the γ‐aminoβ‐hydroxy add moiety of hapalosin is described. The synthetic method features a ring‐opening ethanolysis of an activated N‐Boc‐lactam, which is obtained via a diastereoselective reductive‐alkylation of (R)‐malimide derivative. The flexibility of the method resides in the introduction of the alkyl side chain by Grignard reagent addition.Project supported by the National Science Foundation for Distinguished Young Investigators, the National Natural Science Foundation of China and the Fund for doctoral sites of the Ministry of Education.

Published: September 2010

AbstractThe mononuclear macrocyclic polyamine metal complexes 5a—5e have been shown to form stable 1:1 complexes with bases and nucleosides. Their binding constants (K) were determined by UV‐visible spectrometric titration. The results show that recognition ability of the complexes 5a—5e for uracil, U (Uridine), dT (Thymidine) is higher than that for the other bases or nucleosides (such as Cytidine, Guanosine, Adenosine). The metal ion also plays an important role for the recognition ability of complexes.

AbstractThe synthesis and characterization of the copper (II) complex [Cu2(OOCCH = C(CH3)Fc)3(phen)2]CIO4· 2H2O (1) are reported. The structure of the complex was determined by single‐crystal X‐ray analysis. The compound crystallizes in the monoclinic system, space groupPc, with Z =2,a= 1.2799(4) nm,b=0.9969 (4) nm,c= 2.5228 nm, and β = 91.576 (1) °. The cationic part of 1 indicates a penametallic core in which three 3‐ferrocenyl‐2‐crotonic acid salt (FCA) groups act as (O, O') bridging ligands between two copper (II) ions with a square‐pyramidal environment. Cyclic voltammetric experiments in acetonitrile have been performed mainly to examine the Fe(II) → Fe(III) one‐electron oxidation in FCA and its complex. The variable‐temperature magnetic susceptibility measurements revealed very weak intramolecular anti‐ferromagnetic coupling. Fitting parameters are 2J= ‐0.2 cm−1,g= 2.114, and θ = 0K.

Authors: Zhou Xin , Ren Ai‐Min , Feng Ji‐Kang , Liu Xiao‐Juan , Shu Chia‐Chen 
Published: September 2010

AbstractThe first hyperpolarizabilities of a series of novel azulenic‐barbituric acid chromophores have been studied by using 12 excitation wavelengths, ranging from 900 to 1907 nm. The dispersion relation of the first hyperpolarizabilities of chromophors holds the same tendency as the experimental results. In addition. the static first hyperpolarizability β0 of molecules was calculated by means of the Sum‐Over‐States (SOS) expression and the two‐level formula respectively. The results show that these molecules possess large static fast hyperpolarizabilities and the β0 value increases as the donor or acceptor strength enhances; the distorted degree of molecules has also an important influence on the β0 value.

AbstractThe conductivities of polyethylene oxide (PEO)‐based polymer electrolytes (PE) can be improved by the addition of inorganic inert powder. The composite polymer electrolytes (CPE) PEO10LiX (X = ClO−4 or N(CF3SO2 )2 )‐Li2TiO3 were prepared by solution casting with inorganic solid electrolyte Li2liO3 powder as a filler. Results showed that the conductivities of PEO10LiClO4‐‐3wt% Li2TiO3 and PEO10LiN(CF3SO2)2‐10wt% Li2TiO3 at 30 °C were 8.6×10−‐6 and 5.6×10−‐5 S·cm−l, respectively. The conductivities of CPE increased with the decrease of filler's particle size. The ionic conduction mechanism analysis showed that there may be thee conduction routes in the CPE. i.e., PEO bulk, polymer‐filler interface and Li2TiO3 crystal.
