Orbital-resolved visualization of single-molecule photocurrent channels
Atomic-level imaging of photocurrents in a single molecule is achieved by combining a tunable laser with scanning tunnelling microscopy, revealing how photons turn into electric current via a photoexcited molecule.

Leveraging excited-state coherence for synthetic control of ultrafast dynamics
Information from quantum coherence observations guides synthetic modifications of an iron-based chromophore, increasing the excited-state dynamics lifetime by a factor of 20, with implications for photo-induced electron-transfer applications.

A low-spin Fe(iii) complex with 100-ps ligand-to-metal charge transfer photoluminescence
An iron complex is described that exhibits photoluminescence at room temperature, opening the way to the use of iron-based materials as low-cost, non-toxic light emitters and photosensitizers.

Visualizing coherent intermolecular dipole–dipole coupling in real space
Luminescence induced by highly localized excitations that are produced by electrons tunnelling from the tip of a scanning tunnelling microscope is used to map the spatial distribution of the excitonic coupling in well-defined arrangements of a few zinc-phthalocyanine molecules and the dependence of this spatial distribution on the relative orientation and phase of the transition dipoles of the individual molecules.
