  • 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.

  • Molecular emitters offer a promising solution for single-photon generation. Here, by exploiting electronic decoupling by an ultrathin dielectric spacer and emission enhancement by a resonant plasmonic nanocavity, the authors demonstrate electrically driven single-photon emission from a single molecule.

  • The efficiency of upconversion electroluminescence remains very low for single-molecule emitters. Here, the authors report over one order of magnitude improvement in the emission efficiency via engineering energy-level alignments for triplet relayed upconversion involving only carrier injection.

  • Light harvesting in photosynthesis and photovoltaics may rely on quantum-coherent energy transfer, but experimental verification is hindered by the lossy nature of the molecular systems. Subnanometre-resolved electroluminescence spectroscopy now reveals wavelike intermolecular electronic energy transfer through quantum coherence in artificially constructed donor–acceptor heterodimers at the single-molecule level.

  • Vibronic coupling is a key feature of molecular electronic transitions, but its visualization in real space is an experimental challenge. Here the authors, using scanning tunneling microscopy induced luminescence, resolve the effect of vibronic coupling with different modes on the electron distributions in real space in a single pentacene molecule.
