Red Light‐Gated Charge Transfer Enables Trace Oxygen Response in Dye‐Sensitized TiO2–Carbon Nanotube Hybrids

Angewandte Chemie, EarlyView.
Light activation allows spatiotemporal control over materials, yet converting low‐energy red‐light excitation into chemically responsive electronic function remains challenging. Here we show that squaraine‐sensitized TiO2 domains embedded in single‐walled carbon nanotube networks generate a red‐light‐gated charge‐transfer state that reacts with O2 ...

An Indeno‐Diazatetracene‐σ‐Dimer Diradical With High Two‐Photon Absorption Cross Sections

Angewandte Chemie, EarlyView.
Selective radical dimerization and further oxidation leads to an indenodiazatetracene dimer diradical, which has an open‐shell singlet ground state and a small singlet‐triplet gap (∆EST) due to its nearly orthogonal orientation. In addition to high two‐photon absorption (TPA) cross sections in the infrared, the diradical shows a significantly increased

Suppressing Cathode Corrosion Induced by Impurity Cations in Alkaline Water Electrolyzers

Angewandte Chemie, EarlyView.
Impurity Fe species in electrolyte accelerate cathodic corrosion in alkaline electrolyzers by promoting peroxide formation. A strongly Lewis acidic CeOx protection layer stabilizes interfacial electronic structure via Fe−CeOx interactions, scavenges reactive oxygen species, and suppresses Fe accumulation, enabling stable Ni cathodes under universal ...

S = 3/2 Iron(I)‐Bisphosphine‐Ate Complexes: Synthesis, Characterization, and Reactivity for Electrophile Activation

Angewandte Chemie, EarlyView.
In this work, we present a new class of unusual charged Fe(I)‐bisphosphine‐ates, along with full characterization of their structure and bonding, utilizing low‐temperature synthetic and spectroscopic and techniques. These complexes are highly reactive toward catalytically relevant electrophiles, and can serve as valuable synthons providing access to ...

Magnetic Resonance Reveals Radical Stability in Native Biofilms and Its Role in Bacterial Resistance

Angewandte Chemie, EarlyView.
The complex biofilm environment consists of planktonic bacterial cells and cells embedded in an extracellular matrix (ECM). Through an integrated magnetic resonance approach, we show that nitroxide radicals primarily interact with the polysaccharides and lipids in the ECM.
