In this issue, Marie Pierre Krafft and Jean G. Riess review perfluoropolyhedranes, their electron-accepting ability and questionable supramolecular hosting capacity, and Qiang Zhang et al. summarize 40 years of low-temperature electrolytes for rechargeable lithium batteries. The Minireviews deal with orderly self-assembly of organic fluorophores for sensing and imaging (Xiao-Bing Zhang et al.) as well as alternatives to solvothermal synthetic methods for covalent organic frameworks (Yi Liu et al.). In a Correspondence, Pinghua Liu et al. challenge earlier work on the structure and catalytic mechanism of endoperoxide synthase FtmOx1, and its authors reply.

In the original research section, Katsuhiro Maeda et al. describe a facile synthesis of linear and cyclic poly(diphenylacetylene)s by molybdenum and tungsten catalysis (see picture). Dario R. Dekel observed the migration and precipitation of platinum in anion-exchange membrane fuel cells. Guillermo C. Bazan et al. discovered that a broad light-harvesting conjugated oligoelectrolyte enables photocatalytic nitrogen fixation in a bacterial biohybrid. Xinchen Wang et al. present Rh/Cr₂O₃ and CoO_x cocatalysts for efficient photocatalytic water splitting by poly(triazine imide) crystals.
