Speed Control of Single Molecules on a Surface
Angewandte Chemie, EarlyView.The speed of a single molecule moving across a silver crystal surface is determined with the tip of a scanning tunneling microscope (STM). Travelling distances Δx and travelling times Δt, which are determined simultaneously with high precision, allow to directly measure time–distance relationships.

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 ...
