Zwitterionic Heavier Pnictinidenes in Redox Catalysis

Angewandte Chemie, EarlyView.
Zwitterionic pnictinidenes: A new class of zwitterionic heavier pnictogen species stabilized by bis(N‐heterocyclic carbene)borate ligands is reported, enabling the isolation of Sb and Bi in multiple oxidation states. These thoroughly characterized systems exhibit cationic character and engage in redox catalysis, facilitating catalytic ...

Lignin Dissolution and Direct Ultrasmall‐Lignin‐Nanoparticle Formation in Acidic and Alkaline Deep Eutectic Solvents: A Molecular‐Level Insight

Angewandte Chemie, EarlyView.
Structural interpretation and molecular dynamics simulations reveal how molecular moieties and interaction networks influence the π–π stacking structures and conformational states of lignin during dissolution and aggregation: laterally shifted in deep eutectic solvents, offset‐stacked in tetrahydrofuran, and stretched in dimethyl sulfoxide.

Controlling Assembly of Hybrid DNA Nanostructures into Higher‐Order Structures via Hydrophobicity

Angewandte Chemie, EarlyView.
We harness hydrophobic interactions, fundamental in biology yet underutilized in DNA nanotechnology, to build a design framework for hierarchical DNA assemblies. By conjugating small hydrophobic molecules to DNA motifs, we controlled the formation of higher‐order structures, moving beyond traditional Watson–Crick pairing.

Direct Integration of Functionalized Bridges by One‐Step Superacid‐Catalyzed Reaction to Fabricate Porous Polymers for CO2 Capture and Separation

Angewandte Chemie, EarlyView.
The one‐step polymerization of unfunctionalized polyaromatic monomers and glyoxylic acid under superacid‐catalysis conditions promotes the simultaneous generation of highly porous 3D architectures and the controlled decoration of pore surfaces with aliphatic carboxylic acids. These ultra‐microporous frameworks and their ester and polyionic derivatives,

Hinge‐Like Mechanochromic Mechanophores Based on [2.2]Paracyclophane

Angewandte Chemie, EarlyView.
Hinge‐like supramolecular mechanophores utilizing [2.2]paracyclophane have been developed. In the force‐free state, the rigid [2.2]paracyclophane forces two luminophores into proximity, leading to excimer‐dominant photoluminescence. Stretching the polyurethane films into which the mechanophores are covalently incorporated results in the structures of ...

Trigonal Planar Bis(carbene)Cu(I) Complexes Enable Divergent H2 Activation with H2O for Accelerated Olefin Hydrogenation

Angewandte Chemie, EarlyView.
Trigonal planar naphthyridine‐bis(carbene)Cu(I) alkyl, hydroxide, and ethoxide complexes promote a divergent mechanism of H2 activation for the rare catalytic hydrogenation of unactivated alkenes at mild conditions at copper. Abstract CuH‐catalyzed olefin hydrogenation is rare compared to those of carbonyl‐derived substrates. Olefin insertion into Cu–H
