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 ...
