Incorporation of Organic Counter‐Cations Into Poly(Heptazine Imide) Networks for Promoting Proton‐Coupled Electron Transfer During Photocatalytic H2O2 Evolution

Angewandte Chemie, EarlyView.
Incorporation of N‐based onium ions into the ionic framework of poly(heptazine imide) was obtained via protonation‐deprotonation of PHI frameworks arising from a parent Na‐containing analogue. Particularly, methylammonium moieties, through their small molecular size, hydrogen bonding capabilities and rotational mobility, appear to stabilize ...

Peroxide‐Assisted Solvate Engineering Enables Record‐High Birefringence in a Solar‐Blind Transparent Crystal

Angewandte Chemie, EarlyView.
H2O2‐directed solvate engineering reorganizes ∞[4HP] (4‐hydroxypyridine) chains from a crossed arrangement into a nearly parallel packing through strengthened hydrogen‐bonding interactions. The resulting peroxide‐containing crystal, 4HP·H2O2, exhibits a solar‐blind UV cutoff edge (278 nm) and giant birefringence (0.609 @ 546 nm). This work demonstrates

Antiaromaticity‐Driven Enhancement of Single‐Molecule Electrical Conductance by s‐Indacene Molecular Bridges

Angewandte Chemie, EarlyView.
Within the same molecular length scale, antiaromatic s‐indacene exhibits a marked increase in conductance compared to its aromatic benzodithiophene counterpart. Notably, the inherently small HOMO–LUMO gap of antiaromatic systems maintains a certain level of conductance even in the presence of cross‐conjugation.

Vapor‐Phase Grain‐Boundary Anchoring Enables Molecular Toughening and Record Bending Endurance in Pilot‐Scale Roll‐to‐Roll‐Printed Flexible Perovskite Modules

Angewandte Chemie, EarlyView.
A vapor‐phase molecular toughening strategy is developed for pilot‐scale roll‐to‐roll (R2R) ‐compatible fabrication of flexible perovskite solar modules. Thiol vapor selectively regulates crystallization and anchors at grain boundaries, reducing defects while enhancing mechanical resilience.

Inverse Vulcanization Through Epoxide Chemistry: A Low Temperature Non‐Olefin Route to Sulfur‐Rich Polymer Networks

Angewandte Chemie, EarlyView.
Epoxide monomers undergo base‐catalyzed ring‐opening copolymerization with elemental sulfur to afford sulfur‐rich polymers under mild conditions. The resulting materials exhibit excellent mechanical performance, strong adhesion (up to 10 MPa on stainless steel), and outstanding reprocessability.
