Mechanically Interlocked Indigo Photoswitches

Angewandte Chemie, EarlyView.
By incorporating indigo photoswitches into the axle of a rotaxane, which features a hydrogen bonding macrocycle, we demonstrate improvement in activation wavelength, photostationary states and thermal reversion, an effect that is governed by topologically constrained supramolecular interactions.

Spike‐Embedded Nanocatalysts via Metal‐Directed Carbonization for Highly Efficient and Robust Semi‐Hydrogenation

Advanced Science, EarlyView.
A metal‐directed carbonization strategy transforms hierarchical organic microspheres into spiky carbon catalysts with Pd nanoparticles embedded at the tips. This approach resolves the activity‐stability trade‐off, achieving exceptional poison resistance in semi‐hydrogenations, offering a versatile, scalable platform for designing high‐performance ...

Radical‐Mediated Dispersion Breaks Aggregation Limits in Carbon Thermoelectrics

Angewandte Chemie, EarlyView.
We report a rationally designed small molecule (OTN) that effectively disperses SWCNTs via π–π and radical‐radical interactions, yielding hybrid films with a record power factor of 30.1 µW cm−1 K−2 and excellent flexibility. A nine‐leg device achieves a record normalized power density of 0.653 µW cm−2 K−2, setting a new benchmark for carbon‐based ...

Molecular Design Strategies for High‐Voltage Organic Cathodes

Advanced Energy Materials, EarlyView.
This work proposes molecular engineering strategies for high‐voltage organic cathode materials for Li‐ion batteries: (1) increase Li‐O coordination number (CN), (2) achieve a greater increase in aromaticity upon reduction (∆Aromaticity), and (3) add an electron‐withdrawing group (EWG), through a combined experimental and computational study on reported

Mechanistic Insight Into the Polymorph‐Dependent Photosalient Effect of a White Light or Two‐Photon Activated Photoreactive Molecular Salt

Angewandte Chemie, EarlyView.
Photocycloaddition in stilbene‐type salt polymorphs exhibit distinct light‐driven responses: OHT‐TI shows a violent photosalient effect under visible and NIR (two‐photon) irradiation, whereas OHT‐TII reacts statically. Packing and computational analysis reveals that shell‐like structures in OHT‐TI frustrate structural relaxation, accumulating explosive
