Adsorption of benzene derivatives on allophane

Adsorption of benzene derivatives on allophane
The adsorption properties of benzene derivatives from water on allophane, extracted from soil, have been investigated by UV and FTIR spectroscopic measurements. Allophane adsorbs benzoic acid, phthalic acid, benzaldehyde, ethyl benzoate, and diethyl phthalate. Benzoic acid, phthalic acid, and benzaldehyde formed carboxylate anions on the positive sites

A Neutral “Masked” Diborene and Its Reactivity Toward Metal‐Free Pyridine Homocoupling

Angewandte Chemie, EarlyView.
An unprecedented neutral “masked” diborene, formed via intramolecular arene dearomatization of an N‐heterocyclic imine‐supported free diborene, can be photochemically released to regenerate the highly reactive triplet diborene intermediate. Computational analysis elucidates the bonding situation of the hitherto elusive free diborene species, and the ...

Valency‐Controlled Multiphotochromism: Gated Switching and Photoswitchable Lewis Superacidity at Silicon

Angewandte Chemie, EarlyView.
Multiphotochromic switching is controlled by silicon valency in a diarylethene‐based molecular architecture. Lewis base coordination gates electronic communication between the photochromic units, thereby enabling selective access to distinct switching states.

Upcycling Water Pollutants Into Long‐Chain Polymers via Synergistic Interfacial Dechlorination and Organic Radical Stabilization

Angewandte Chemie, EarlyView.
HEO‐regulated electronic structure drives nonradical PI activation, promoting ETP‐mediated polymerization of 4CP into high‐molecular‐weight products with enhanced surface enrichment. Concurrent dechlorination occurs via radical coupling and •OHads attack, enabling efficient carbon retention and selective product evolution at the liquid–solid interface.

A Borane Sandwich Analogue of Ferrocene

Angewandte Chemie, EarlyView.
The first ferrocene analogue with two boron‐based ligands is identified through a global exploration of the FeB10H20 potential energy surface. The η5,η5‐Fe(B5H10)2 complex emerges as the global minimum, showing that metal coordination inverts borane stability and enables aromatic boron rings inaccessible in isolation.

Catalyst Hide‐and‐Seek Beneath Porous Support Surfaces: Pinpointing Active Site Distribution Through Resonance Energy Transfer

Angewandte Chemie, EarlyView.
Like a shark playing hide‐and‐seek in a coral reef, energy transfer (ET) finds hidden “fish” catalysts in the porous support “reef.” ET allows catalytic species to be precisely mapped, revealing whether they reside near the surface, deep in the pores, or are uniformly distributed. This approach ensures controlled catalyst distribution, highlighting how
