The carbonization of aromatic molecules with three-dimensional structures affords carbon materials with controlled pore sizes at the Ångstrom-level

Porous carbon materials are used widely in catalysis, electrochemistry, or as sorbents, but pore size control continues to be a challenge in their syntheses. Here the authors show that the 3D molecular structure of the carbon sources allows to control the pore size of the resulting carbon materials at the Ångstrom-level.

Ring shape-dependent self-sorting of pillar[n]arenes assembled on a surface

Self-sorting is an attractive approach to produce complex supramolecular systems and materials with controlled structures. Here the authors show geometrical complementarity in the self-sorting behaviour of pentagonal and hexagonal pillararenes on heterogeneous surface through layer-by-layer deposition.

Molecular weight fractionation by confinement of polymer in one-dimensional pillar[5]arene channels

Confinement of polymers in nano-spaces can induce unique molecular dynamics and properties. Here the authors show high mass fractionation by the confinement of single polymer chains of poly(ethylene oxide) in the one-dimensional channels of crystalline pillar[5]arene.

Transparent ionic liquid-phenol resin hybrids with high ionic conductivity

We report transparent ion conductive ionic liquid-phenol resin hybrids prepared by in situ polymerization/crosslinking of phenol monomer in ionic liquid. The transparent hybrid prepared from 20 wt% monomer concentration exhibited high thermal stability and ionic conductivity (1.0 × 10⁻³ S cm⁻¹ at 30 °C), which is comparable to the pristine ionic liquid.

Extension of polyethylene chains by formation of polypseudorotaxane structures with perpentylated pillar[5]arenes

Melt mixing of high-density polyethylenes and wheels of perpentylated pillar[5]arenes resulted in formation of polypseudorotaxane structures. Formation of the polypseudorotaxane structures led to extension of the high-density polyethylene chains, and dramatically increased the melting point of high-density polyethylene from 126 to 152 °C. We demonstrated molten state-to-solid and solid-to-molten state transitions of high-density polyethylene based on the host–guest system.

Pillar[6]arene acts as a biosensor for quantitative detection of a vitamin metabolite in crude biological samples

Quick and accurate measurements of specific metabolites are critical to diagnose certain pathological conditions, but quantification methods for relatively low molecular-weight metabolites are limited. Here, the water-soluble pillar[6]arene is used to specifically and quantitatively detect 1-methylnicotinamide in crude urinary samples.
