Engineering Metal‐Pocket Cooperativity in Single‐Atom COF Nanozymes for Selective Cascade Catalysis
Advanced Materials, EarlyView.A multilevel programming strategy is developed to engineer single‐atom COF nanozymes with tunable metal centers and chiral pockets inspired by heme–pocket cooperativity. This approach enables controlled metal–pocket interplay for asymmetric cascade catalysis, delivering high activity, selectivity, and recyclability in an asymmetric oxidation–aldol ...

Advanced Materials, EarlyView.Alkoxy chain length drives a continuous transition from eclipsed AA to a serrated, slipped AA* configuration over Co‐porphyrin COFs. A moderate slip both contracts the pore channel to enrich CO2 and suppress hydrogen evolution, and enhances collective high‐spin of Co sites, which delivers a record CO production rate with high selectivity.

Properties of conjugated Schiff bases of malonaldehyde.
Chemical and Pharmaceutical Bulletin, 1986 Malonaldehyde is one of the end products of lipid oxidation, and because of its bifunctionality it can produce a conjugated Schiff base with a primary amine. The fluorescence properties, the reactivity to thiobarbituric acid (TBA) and the antioxidative activity of conjugated Schiff bases of malonaldehyde and aniline (I1), p-toluidine (I2), p-anisidine (
