      The cover picture shows a new coordination polymer, [Co2(L)2(4,4′-bipy)]n·3nH2O (1) based on 5-(3-methyl-5-phenyl-4H-1,2,4-triazol-4-yl)isophthalic acid (H2L) and 4,4′-bipyridine (4,4′-bipy), which has been hydrothermally synthesized and characterized by single-crystal X-ray diffraction, XRPD, IR, and elemental analysis. The 2D triangle networks were linked by the bridging 4,4′-bipy ligand to give rise to a 2-fold interpenetrated 3D architecture. We can define Co(II) ions as 4-connected nodes and the L2− ligands as 3-connected nodes. Thus, the 3D structure can be described as a 2-fold parallel interpenetrated ins InS 3,4-conn topology. Variable-temperature (2–300 K) magnetic susceptibility measurements indicate that compound 1 exhibits antiferromagnetic interactions between the Co(II) paramagnetic centers. Compound 1 was heated to produce Co3O4. The particle size of the Co3O4 phase is 400–800 nm. More details are discussed in the article by Liu et al. on page 227232.

      Four 1,8-naphthalimide hydrazone molecules with different electron donor groups have been applied in the study of linear and nonlinear optical (NLO) properties. Through the modification of the structure, the nonlinear optical properties of these compounds at different wavelengths (532 nm and 800 nm) were well tuned.

    7. All-Atom Molecular Dynamics Simulation of Structure and Diffusion of Hydrophilic Antistatic Agents in Polypropylene (pages 248–256)

      Lianhua Long, Yingzi Yang and Feng Qiu

      Article first published online: 5 MAR 2014 | DOI: 10.1002/cjoc.201300843

      Based on glycerol monostearate, we propose five additives of different polarity by attuning the number of oxyethyl groups. When embedded in polypropylene matrix, due to the gauche effect of the dihedral angles, the polar parts of these additives form helix structures. The diffusion coefficient of the additives depends on their molecular conformations and decreases monotonously with increasing polarity. These results are expected to be helpful in rational design of hydrophilic antistatic agents in polymeric materials.

    10. Accurate Prediction of Ir[BOND]H Bond Dissociation Enthalpies by Density Functional Theory Methods (pages 269–275)

      Yi Zhou, Dingjia Liu, Yao Fu, Haizhu Yu and Jing Shi

      Article first published online: 5 MAR 2014 | DOI: 10.1002/cjoc.201400015

      The accuracies of different theoretical methods (including different density functional theory methods, basis sets and solvation models) in prediction of the Ir[BOND]H BDEs have been examined. It is found that the TPSS/(LanL2DZ: 6-31G(d)) method is relatively more accurate than the other gas-phase calculation methods, and can well simulate the Ir[BOND]H BDEs in low-polarity solvents (such as chlorobenzene and dichloroethane).
