      Cover Picture: Synthesis, Characterization and Properties of Novel Star-Shaped π-Conjugated Oligomers with Triphenylamine Core (Chin. J. Chem. 4/2013) (page 433)

      Leijing Liu, Qing Guo, Jiyang Li, Bin Yao and Wenjing Tian

      Article first published online: 15 APR 2013 | DOI: 10.1002/cjoc.201390008

      The cover picture shows four novel star-shaped π-conjugated oligomers. The core of these new star-shaped oligomers is electron-donating group, triphenylamine. The peripheral units are four hole-transporting chromophores with different electron-donating ability. The photophysical properties of these oligomers can be tuned through changing the electron-donating ability and conjugation length of the peripheral units. The fluorescence quenching properties indicate that efficient charge transfer can happen between the star-shaped oligomers and EP-PDI. More details are discussed in the article by Tian et al. on page 456–464.

      Using enantiopure α-amino acids as chiral sources, a series of novel axially chiral 2,2′-bipyridine N,N′-dioxides bearing C1 or C2-symmetry have been designed and synthesized in this work. The absolute stereochemistry of the axial chirality of these organocatalysts has been clearly assigned by means of CD measurements together with literature protocols. These chiral organocatalysts have shown the moderate reactivities and enantioselectivities in the asymmetric allylation of aromatic aldehydes with allyltrichlorosilane with up to 67% yield and up to 65% ee.

      Several molecular hydrogels based on naphthylacetic acid-peptides containing L-histidine were formed by the heating-cooling process. All hydrogels exhibited higher activity to hydrolyze 4-NPA than the free L-histidine probably due to the high density of L-histidine residue at the surface of self-assembled nanofibers.

      A novel method for fast determination of ethylendiamine (EDA) in Aminophylline Tablets has been developed by small-sized capillary electrophoresis with amperometric detection (small-CE-AD) coupled with field-amplified sample injection (FASI). Under the optimum conditions, EDA (peak 1) and four aliphatic diamine homologs (1,3-diaminopropane, 1,4-diaminobutane, 1,5-diaminopentane and 1,6-diaminohexane) could be well separated within 6 min at a separation voltage of 2.0 kV in an acetate buffer solution of pH 3.8 with low limit of detection of 1.3×10−11 g/mL for EDA (S/N=3). The method does not require off-line preconcentration and derivatization steps.

      Copper hydride ligated with DPEphos or Xantphos ligand could catalyze conjugate reductive intermolecular aldol addition domino reactions of α,β-unsaturated carboxylates with ketones using a silane as the reducing reagent. High diastereoselectivities were achieved using tert-butyl acrylate as the hydride acceptor in the presence of Xantphos.

    15. Fast Determination of Phenanthrene in Soil by Gas Chromatography-Mass Spectrometry Using Chemometric Resolution and Standard Addition Method (pages 545–550)

      Weiwei Yu, Wensheng Cai and Xueguang Shao

      Article first published online: 3 APR 2013 | DOI: 10.1002/cjoc.201300004

      Thumbnail image of graphical abstract

      Gas chromatography-mass spectrometry is used for fast determination of phenanthrene in soil with the help of chemometric resolution. In this method, clean-up steps were overleaped and a short capillary column and fast temperature program were used for speeding up the analysis. Due to the complex matrix in the samples, window independent component analysis (WICA) and non-negative immune algorithm (NNIA) were used for retrieving the signal of the target component. The proposed method was applied to the quantitative analysis of soil samples by standard addition method and acceptable results are obtained.
