Synthesis and Characterization of New Soluble Polyamides from 9,9‐Bis[4‐(chloroformylphenoxy)phenyl]xanthene and Various Aromatic Diamines
Authors: Jiang Jianwen , Huang Shuiping , Liu Yuan , Sheng Shouri , Huang Zhenzhong , Song Caisheng 
Published: February 2010

Abstract9,9‐Bis(4‐hydroxyphenyl)xanthene (BHPX) was synthesized in 82% yield from xanthenone in a one‐pot, two‐step synthetic procedure. A new diacyl chloride monomer, 9,9‐bis[4‐(chloroformylphenoxy)phenyl]xanthene (BCPX), was synthesized in three steps from the nucleophilic fluorodisplacement of 4‐fluorobenzonitrile with the dipotassium bisphenolate of BHPX, followed by alkaline hydrolysis of the intermediate bis(ether nitrile), and then chlorination with thionyl chloride. Several novel aromatic polyamides containing ether and bulky xanthene groups with the inherent viscosities (0.72–0.98 dL/g) were prepared by the low temperature polycondensation of BCPX with various aromatic diamines in N,N‐dimethylacetamide (DMAc) solution containing pyridine (Py). All new polyamides were amorphous and readily soluble in various polar solvents such as DMAc, N,N‐dimethylformamide (DMF), N‐methyl‐2‐pyrrolidone (NMP) and Py. These polymers showed relatively high glass transition temperatures between 236 and 298°C, decomposition temperatures at 10% weight loss ranging from 490 to 535°C and 483 to 515°C in nitrogen and air, respectively, and char yields at 700°C in nitrogen higher than 50%. Transparent, flexible, and tough films of these polymers cast from DMAc solutions exhibited tensile strengths ranging from 82 to 106 MPa, elongations at break from 10% to 25%, and initial moduli from 2.0 to 2.8 GPa.
Performance Improvement of Organic Light Emitting Diodes Using Poly(N‐vinylcarbazole) (PVK) as a Blocking Layer
Authors: Lee Joo‐Won , Kim Jai‐Kyeong , Yoon Young‐Soo 
Published: February 2010

AbstractHigh efficiency organic light‐emitting‐devices (OLED) have been fabricated by incorporation of a polymeric layer as a controller of the unbalanced charge. In device configuration of ITO/PEDOT:PSS/PVK/Alq3/LiF:Al, poly(N‐vinylcarbazole) (PVK) was selected as a block‐ing layer (BL) because it has a hole transporting property and a higher band gap, especially a lower LUMO level than the emitting layer (Alq3) and a higher HOMO level than the hole injection layer (PEDOT: PSS). As a result, the optimal structure with this bl layer showed a peak efficiency of 6.89 cd/A and 2.30 lm/W compared to the device without the PVK layer of 1.08 cd/A, 0.27 lm/W. This result shows that the PVK layer could effec‐tively block the electrons from metal cathode and confine them in the emitting layer and accomplish the charge balance, which leads to enhanced hole‐electron balance for achieving high recombination efficiency.
Enantioselective Partitioning of Racemic Ibuprofen in a Biphasic Recognition Chiral Extraction System
Authors: Tang Kewen , Song Litao , Pan Yang , Jiang Xinyu , Miao Jiabing 
Published: February 2010

AbstractEnantioselective partitioning of ibuprofen enantiomers in a biphasic recognition chiral extraction system was studied. A combination of hydrophobic L‐isobutyl tartrate in organic phase and hydrophilic β‐cyclodextrin derivative in aqueous phase is necessary to establish a biphasic recognition chiral extraction system. The studies performed involve an enantioselective extraction in a biphasic system, where ibuprofen enantiomers form four complexes with the β‐cyclodextrin derivative in aqueous phase and the D(L)‐isobutyl tartrate in organic phase, respectively. In these biphasic resolutions, the types and the concentrations of the extractants, pH and temperature all exert a considerable influence on the biphasic recognition process. Good enantioselectivities for ibuprofen enantiomers were obtained at pH≦2.5 and a ratio of 2:1 of [L‐isobutyl tartrate] to [HP‐β‐CD]. Biphasic recognition chiral extraction is of strong chiral separation ability, and may be very helpful to optimize the extraction systems and realize the large‐scale production of enantiomers.

Pd/C‐catalyzed Reductive Mono‐N‐alkylation of Nitrophenol Derivatives in One‐pot Way
Authors: Jin Zhonghao , Li Dao , Wang Xingyi , Xiao Qin 
Published: February 2010

AbstractA range of different nitrophenol derivatives were converted in one‐pot to the corresponding secondary alkyl aminophenols in good to excellent yields by using ketones as alkyl source and hydrogen over 10 wt% Pd/C as reducing agent. In all examples, except for one, the secondary amine was the sole alkylation product isolated. When aldehydes were used as alkyl source, the corresponding tertiary amine as a sole alkylation product was isolated.
Molecular Dynamics Simulation of HIV‐1 Integrase Dimer Complexed with Viral DNA
Authors: Hu Jianping , Wang Cunxin 
Published: February 2010

AbstractThe biological function of HIV‐1 integrase (IN) is to integrate viral DNA into the host cell chromosome, and the specific binding of IN with viral DNA is a precondition for IN to function correctly. Beforehand, the binding mode of IN dimer (IN2) with the 27 bp segment of viral DNA before 3′ processing (3′‐P) was obtained via a molecular docking method. Based on the binding mode, the aim of this article was to explore the changes of motive mode and correlative motion for the IN2 and DNA systems after their binding through dynamical cross‐correlation map (DCCM) and principal component analysis (PCA). Finally, solvent effect during the association was analyzed briefly. The results show that there is a significantly increased positive correlation in the interface region between IN2 and viral DNA, and some obvious motive mode changes of the two systems (IN2 and DNA) were also observed after their binding. It was found that water molecules played an important role in the recognition between IN2 and viral DNA through analyzing the water‐mediated hydrogen bonds.
Synthesis, Structure and Anticancer Activity Studies of 1‐[(5‐Bromo‐2‐thienyl)sulfonyl]‐5‐fluoro‐1,2,3,4‐tetrahydropyrimidine‐2,4‐dione
Authors: Miao Qian , Yan Xiaowei , Zhao Kejian 
Published: February 2010

AbstractAn anticancer active compound 1‐[(5‐bromo‐2‐thienyl)sulfonyl]‐5‐fluoro‐1,2,3,4‐tetrahydropyrimidine‐2,4‐dione (1) was synthesized by the modified Schotten‐Baumann reaction of 5‐fluorouracil with 5‐bromo‐2‐thienyl‐sulfonyl chloride and characterized by elemental analysis, IR, 1H and 13C NMR spectra. The single crystal X‐ray diffraction analysis shows that the title molecule forms a two dimensional sheet structure by three kinds of hydrogen bond interactions. Its thermal stability was studied by TGA technique. Based on inhibition ratio against cancer cell growth, compound 1 has obvious anticarcinogenic activity against HL‐60 and BEL‐7402 cancer cells.
Microwave Assisted One‐pot Synthesis of 2‐Amino‐4H‐chromenes and Spiropyrano[2,3‐d]pyrimidine
Authors: Mahmoud Alaa F. , Abd El‐Latif Fathy F. , Ahmed Amira M. 
Published: February 2010

AbstractA convenient and efficient method using microwave assisted one pot synthesis reactions for synthesis of 4H‐benzo[f]chromenes by the reaction of aromatic aldehydes with a mixture of malononitrile and naphthols was examined. The synthesis of spiropyrano[2,3‐d]pyrimidines by the reaction of isatin with malononitrile and barbituric acid and/or thiobarbituric acid was investigated. The versatility of the method was also examined through the reaction of aromatic aldehydes and malononitrile with various reagents.
An implicit LU‐SGS spectral volume method for the moment models in device simulations: Formulation in 1D and application to a p‐multigrid algorithm
Authors: Kannan Ravishekar 
Published: February 2010

AbstractA high‐order spectral volume (SV) method was implemented for solving the steady‐state moment models, such as the hydrodynamic (HD) models and the energy transport (ET) models for semiconductor device simulations (in 1D). The first derivative inviscid/convective fluxes are handled using an approximate Riemann flux and the second derivative diffusive fluxes are discretized using the local discontinuous Galerkin formulation (LDG). The LDG method is also used for discretizing the potential equation. An implicit pre‐conditioned LU‐SGS p‐multigrid method developed for the SV Navier–Stokes (NS) solver by Kannan and Wang is adopted here for time marching. The entire formulation is compact and hence can be easily parallelized. A n+‐n‐n+ diode was assumed for simulation purposes and the results are compared with the existing discontinuous Galerkin simulation results. In general, the numerical results are very promising and indicate that the approach has a great potential for higher‐dimensional device problems. Copyright © 2010 John Wiley & Sons, Ltd.
