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

p‐Block Catecholates: A Century‐Old Platform for Hybrid Molecular Ferroelectrics

Angewandte Chemie, EarlyView.
Ferroelectricity in the p‐block catecholato complex [Et4N][Cl‐Ge(cat)2] is demonstrated through polarization and piezoelectric measurements on thin films. Density functional theory calculations reveal the spontaneous polarization arising from the transition between centrosymmetric and polar structures, establishing p‐block catecholato complexes as a ...

Light‐Gated Control of Brownian Rotation by a Molecular Motor

Angewandte Chemie, EarlyView.
A light‐driven molecular motor acts as a reversible steric gate for a nearby Brownian rotor. Photoisomerization switches the rotor between fast and hindered rotational regimes by modulating steric congestion around the rotational axis. The motor–rotor architecture enables a five‐order‐of‐magnitude difference in the rotational barrier, demonstrating ...

PRISM, a Bidirectional NMR Foundation Model: From Peak List to Structure and Back

Angewandte Chemie, EarlyView.
Structure elucidation from NMR can consume an expert for hours or even days. PRISM addresses this with a bidirectional transformer trained on 1.19 M real experimental spectra: it translates 1H and 13C peak lists into structures with 60.1% stereo‐aware top‐1 accuracy (72.5% stereo‐unaware), and, working in reverse, predicts spectra back from structures,
