Real-space investigation of energy transfer in heterogeneous molecular dimers
Scanning tunnelling microscopy is shown to be effective for probing energy transfer in a molecular dimer with submolecular resolution in real space.

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.

Long-range energy transport in single supramolecular nanofibres at room temperature
Coherent energy transport is key to the operation of the photosynthetic machinery and the successful implementation of molecular electronics; self-assembled supramolecular nanofibres based on carbonyl-bridged triarylamines are now shown to transport singlet excitons over micrometre-scale distances at room temperature.

Highly efficient organic light-emitting diodes from delayed fluorescence
A class of metal-free organic electroluminescent molecules is designed in which both singlet and triplet excitons contribute to light emission, leading to an intrinsic fluorescence efficiency greater than 90 per cent and an external electroluminescence efficiency comparable to that achieved in high-efficiency phosphorescence-based organic light-emitting diodes.
