      The cover picture shows a novel pillar[5]arene entirely with both hydroxyl and methoxycarbonyl-methoxy groups and its host-guest property with a bis(imidazolium) salt. Pillararene, since it was first reported in 2008, has attracted a rising interest from many supramolecular chemists. Opportunities and challenges coexist in selective functionalization of pillararenes. Our group used a facile strategy (partial oxidation and reduction) to obtain the pillar[5]arene entirely with two types of functional groups from the initial starting compound, 1,4-dimethoxypillar[5]arene (DMP[5]). Its self-assembly in the solid state showed that a water molecule had triple bonding with the host, which implied its potential application in new type of proton transmembrane channels. Thanks to this regioselective preparation, the host-guest property of this pillararene with a bis(imidazolium) salt was studied. More details are discussed in the article by Xue et al. on page 128–132.

      By the introduction of methoxycarbonyl-methoxy groups and hydroxyl groups into a pillar structure, a pillararene entirely with two types of functional groups was successfully prepared, which can form a stable 1:1 complex with a bis(imidazolium) salt in CHCl3/acetone solution (V:V=1:1).

    3. Self-assembly of DNA Origami Using Rolling Circle Amplification Based DNA Nanoribbons (pages 137–141)

      Article first published online: 14 JAN 2014 | DOI: 10.1002/cjoc.201300827

      We present a novel strategy to assemble the DNA origami using rolling circle amplification based DNA nanoribbons as the linkers. Firstly, long single-stranded DNA from Rolling Circle Amplification is annealed with several staples to form kinds of DNA nanoribbons with overhangs. Subsequently, the rectangle origami is formed with overhanged staple strands at any edge that would hybridize with the DNA nanoribbons. By mixing them up, we illustrate the one-dimensional even two-dimensional assembly of DNA origami with good orientation.

    4. Synthesis and DNA Cleavage Properties of Triazacrown Derivatives (pages 142–150)

      Mingfeng Fang, Li Wei, Zhongxiang Lin and Guo-Yuan Lu

      Article first published online: 14 NOV 2013 | DOI: 10.1002/cjoc.201300699

      The conjugate 1 of 1,4,7-triazacrown with aminoethyl, hydroxyethyl side arms and a anthraquinone was prepared as new metal-free reagents for DNA cleavage. DNA-binding property and DNA cleavage activities were investigated by fluorescence spectroscopy and agarose gel electrophoresis. Radical scavenger inhibition study suggests that DNA cleavage promoted by 1 may be a non-oxidative pathway through the transphosphorylation and then hydrolysis.
