Competing Charge Separation Pathways Govern Charge Generation in Organic Photovoltaic Blends: Insights From Transient Electron Spin Resonance

Advanced Energy Materials, EarlyView.
Transient electron spin resonance distinguishes interfacial charge‐transfer states from separated charges, revealing competing charge separation pathways in organic photovoltaic blends. The relative contributions of fast charge separation and a pathway mediated by spin‐polarized charge‐transfer states vary across different blends, with high‐efficiency ...

Gold Clusters With Open‐Shell Ligands: Superatom Mediated Magnetic Interaction

Angewandte Chemie, EarlyView.
Open‐shell verdazyl radicals were covalently integrated with atomically precise Ir‐doped Au12 (Ir@Au12) superatoms. The resulting radical–superatom hybrids exhibit photoinduced electron transfer, spin delocalization onto the metal‐cluster core, and weak ferromagnetic communication between radicals mediated by the superatomic electronic structure ...

Indium Clusters With 6s2 Lone‐Pair Effect as Excitonic Electron Reservoirs for Direct 2e− Photocatalytic H2O2 Photosynthesis

Angewandte Chemie, EarlyView.
This study demonstrates that indium clusters with 6s2 lone‐pair effect anchored on carbon nitride act as excitonic electron reservoirs to boost charge separation and O2 activation for highly selective direct 2e− oxygen reduction. This work establishes cluster‐mediated electron reservoir engineering as a general strategy for enhancing selective ...

Conformationally Switchable Copper(I) Complexes Amplify BODIPY Triplet Photosensitization

Angewandte Chemie, EarlyView.
Coupling a structurally switchable Cu(I) complex to an organic light‐harvesting chromophore boosts photoinduced intersystem crossing via the transient formation of a Cu(II) intermediate. Spectroscopic, physical, computational, and photocatalytic studies support this unique new approach to solar energy upconversion.

Beyond Radical Emitters: Hot‐Exciton Electroluminescence From Singlet Diradicaloids

Angewandte Chemie, EarlyView.
The first hot‐exciton mechanism in a singlet diradicaloid is demonstrated in a polychlorinated Thiele hydrocarbon‐based organic light‐emitting transistor. Reverse intersystem crossing involving the T2 and bright singly excited states enables electroluminescence beyond the 25% spin‐statistical limit, leading to remarkable external quantum efficiency ...
