      Cover Picture: Cocrystal Assembled by 1,2-Diiodotetrafluorobenzene and Acridine via C[BOND]I···N Halogen Bond and π-hole···F Bonds (Chin. J. Chem. 10/2013) (page 1237)

      Article first published online: 18 OCT 2013 | DOI: 10.1002/cjoc.201390024

      The cover picture shows a cocrystal with repeated 8-F-atom unit as basic structural motif, which is assembled based on combination of bifurcated C[BOND]I···N···I[BOND]C σ-hole bond and antiparallel double π-hole···F bonds by 1,2-diiodotetrafluorobenzene and acridine. The concepts on the σ-hole and π-hole bonds are suggested based on the physical framework, the molecular surface electrostatic potential, which can be considered as another nomenclative system of fashionable halogen/chalcogen/pnicogen/silicogen bonds and anion-π interaction, respectively. The combination of the two bonds or together with other weak interactions could play a key role in assembling function materials, molecular recognition and design of drugs and so on. More details are discussed in the article by Jin et al. on page 1279–1284.

      Article first published online: 26 JUL 2013 | DOI: 10.1002/cjoc.201300423

      Thumbnail image of graphical abstract

      In this paper, highly dispersive nanosized copper particles with a mean particle size of less than 6 nm are prepared by an environmentally friendly chemical reduction method. Non-toxic L-ascorbic acid acts as both reducing agent and antioxidant in ethylene glycol in the absence of any other capping agent. Transmission electron microscopy (TEM) is used to characterize the size and morphology of Cu nanoparticles. The results of UV-Vis spectroscopy (UV-Vis), energy dispersive spectroscopy (EDS) and high resolution TEM (HRTEM) illustrate that the resultant product is pure Cu nanocrystals. The size of Cu nanoparticles is remarkably impacted by the order of reagent addition, and the investigation reveals the reaction procedure of Cu2+ ions and L-ascorbic acid.
