The cover picture shows a novel porous organic polymer (POP) which was constructed through the condensation of triptycene tricatechol and 1,3,5-benzenetris(4-phenylboronic acid). POPs are a kind of organic materials which possess permanent porosity and thus have great potentials in the field of gas storage and separation. The as-prepared triptycene- based POP exhibits high H₂ uptake (up to 1.84 wt% at 77 K, 1 bar), large CO₂ adsorption capacity (up to 18.1 wt% at 273 K, 1 bar), and excellent CO₂/N₂ adsorption selectivity (up to 120/1). The influence of solvent on the gas adsorption performance of the POP has also been investigated. More details are discussed in the article by Zhao et al. on page 539–544.

Amphiphilic DNA organic hybrids, containing DNA and organic molecules, e.g., polymer, dendron and lipid, self-assemble into a series of morphologies. Utilizing DNA hybridization, enzymatic activity and secondary structure, the morphologies of assemblies could be precisely regulated.

The palladium-catalyzed direct C2- and further C7-acylation of indoles with aldehydes have been developed. This method provides a convenient pathway toward a variety of mono- and diacylated indoles.

Here, we present a protocol for the assembly of DNA nanoribbons with only four oligonucleotides. DNA nanoribbons with different dimensions were successfully assembled with a 96-base scafford strand and three short staples. This approach suggests that there exists a vast design space for the creation of simple nucleic acid nanostructures which could facilitate their application in plasmonic or drug delivery.

Monodisperse hybrid Janus nanofibers with the structure that one Au nanoparticle (AuNP) is connected to one end of a polymeric nanofiber were prepared by the self-assembly between polymeric micelles and the tadpole-like conjugates resulting from one-to-one complexation of long DNA chains with AuNPs.

A practical copper-diphosphine catalytic system was applied in the asymmetric hydrosilylation of aromatic ketones, in which inexpensive non-toxic polymethylhydrosiloxane was first efficiently used as reducing agent in air atmosphere and at room temperature.

A series of ionic liquids which possess the same cation and different anions were synthesized to explore the effect of anions on 5-hydroxymethylfurfural (HMF) preparation from glucose over AlCl₃. Systematic experiments showed that N-methyl-2-pyrrolidone bromide ([NMP]Br) could promote selective conversion of fructose. Theoretical study indicated that Br⁻ could also combine with Al³⁺, accelerating process of H-shift during glucose isomerization. This discovery can help us choose cocatalysts for low toxic metal, realizing selective conversion of cellulosic biomass conversion.
