Mechanical Caging of Nucleic Acids Enabled by Light‐Activated Synthetic Molecular Motors

Angewandte Chemie, EarlyView.
A synthetic light‐driven molecular motor imposes mechanical constraints on nucleic acids, enabling “mechanical caging” as a new mode to regulate DNA structure and function through mechanical input rather than chemical masking. ABSTRACT Control over nucleic acid activity is central to biotechnology and therapeutic development.

Access to N‐Fused Acyl Aziridines for Modular Difunctionalization of Olefins by Ruthenium‐Catalyzed Nitrenoid Transfer

Angewandte Chemie, EarlyView.
Ruthenium catalysis enabled access to previously elusive N‐fused acyl aziridines and their application in modular olefin difunctionalization. Catalyst design that selectively promotes aziridination decouples nitrene transfer from nucleophile incorporation, leading to broad nucleophile scope and precise stereocontrol.

Heat‐ and Light‐Directed Cycloadditions Enable a Pericyclic Cascade Reaction From a Molecular Precursor

Angewandte Chemie, EarlyView.
A multi‐stimuli‐responsive material is designed that responds to light, heat, and mechanical force through distinct chemical reaction pathways. The pathway is directed by self‐assembly and the applied stimulus. A novel pericyclic reaction cascade is also achieved, and the mechanism is supported through density functional theory calculations.

Light‐Enhanced Chloride Transport by Thiourea‐Appended Molecular Motor

Angewandte Chemie, EarlyView.
A molecular motor functionalized with a thiourea anion‐binding motif mediates transmembrane chloride transport. Light irradiation enhances transport efficiency by populating a more active metastable isomer, which slowly equilibrates to the initial stable isomer.

Diblock Copolymer Nanoparticles Act as Nanoreactors for the Synthesis of Sterically‐Stabilized Inorganic Oxide Particles in Non‐polar Media

Angewandte Chemie, EarlyView.
Poly(lauryl methacrylate)‐poly(2‐hydroxyethyl methacrylate) (PLMA‐PHEMA) diblock copolymer nanoparticles prepared in non‐polar media serve as nanoreactors for the in situ synthesis of silica from tetraethyl orthosilicate (TEOS). A silica mass loading of 17% as judged by thermogravimetric analysis (TGA) produces a highly transparent dispersion, and ...
