The syntheses of poly[2]catenane gels reported to date all rely on the polymer as the backbone. We reported poly[2]catenane gels prepared by entirely sequential self-assembly of small molecules via noncovalent and dynamic covalent bonds. Due to the presence of hydrogen bonds in the poly[2]catenane gels, the gels also possessed stimulus responsiveness and self-healing properties. More details are discussed in the article by Ji et al. on pages 2699—2704.

Practical CO₂ and CO electroreduction are often operated at elevated temperatures, yet the correlation between the temperature increase and catalytic activity and selectivity has not been well-defined. This study uncovers that higher temperatures enhance *CO coverages, but in CO₂ reduction, they also promote *CO desorption to vapor-phase CO, lowering C₂H₄ selectivity. In CO reduction, elevated temperatures facilitate CO diffusion to overcome the unfavorable *CO adsorption thermodynamics, which promotes C—C coupling. More details are discussed in the article by Wang et al. on pages 2705—2711.

We reported poly[2]catenane gels prepared by entirely sequential self-assembly of small molecules via noncovalent and dynamic covalent bonds. First, monomer M1 self-assembled into linear supramolecular polymers through hydrogen bonding and π-π interactions. Upon the addition of M2 and M3, dynamic covalent bonds were generated to transform supramolecular polymers into poly[2]catenane gels.

This study focuses on the effect of temperature on the kinetics and product selectivity of CO₂ and CO electroreduction. Although the elevated temperature increases *CO coverages in both reactions, it promotes *CO desorption in CO₂ reduction but increases C—C coupling activity in CO reduction, causing the observed differences in selectivities.
