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 227–232.

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.

The classical Ullmann CS cross coupling reaction of aryl iodides with aromatic/alkyl thiols under catalysis of 15 mol% Cu(OAc)₂·H₂O and 15 mol% 2,2′-biimidazole works at 80°C in DMSO for 3 h to provide a variety of aryl sulfides in good to excellent yields.

Multicomponent methodology for the synthesis of both N-substituted and NH containing 1,4- dihydropyridines has been achieved by employing the key activation of secondary amine to electron deficient terminal alkynes.

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) has been hydrothermally synthesized and characterized by single-crystal X-ray diffraction, XRPD, IR, and elemental analysis. Temperature-dependent magnetic susceptibility and thermal degradation for 1 were also studied. A 2-fold parallel interpenetrated ins InS 3,4-conn topology has been obtained.

Pt can be deposited on WC/RGO by galvanic displacement with Cu. With the increasing of deposition, the extent and domain of Pt loading affect the electrochemical performance.

(−)-Menthyl (S)-6′-acrylyl-2′-methyloxy-1,1′-binaphthalene-2-carboxylate 3 ([α]_D²⁵=−72.4) was synthesized and anionically polymerized using n-BuLi as an initiator to obtain poly-3 ([α]_D²⁵=+162.0) which has been proved to take one-handed helical backbone in solution.

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.

Au/TiO₂ catalyst is firstly reported to be efficient in the hydrogenation of nitrobenzene to produce p-aminophenol with a high PAP selectivity of 81% and overall yield more than 63%. The catalyst is also quite stable and can be reused for at least 4 times with only slight decrease in activity.

Horseradish peroxidase entrapped in a low molecular weight gel has a pair of well-defined and quasi-reversible redox peaks on glassy carbon electrode with the heterogeneous electron transfer rate constant being 14.4 s⁻¹.

The accuracies of different theoretical methods (including different density functional theory methods, basis sets and solvation models) in prediction of the Ir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H BDEs in low-polarity solvents (such as chlorobenzene and dichloroethane).

A modified synthetic route of [3,3′-di-sec-butyl-4′-(2-dimethylaminoethoxy)biphenyl-4-yloxy]acetic acid (1) with high total yield of 44% from biphenyl-4,4′-diol (2) is described.
