Dynamic duos
The discovery of intermediate high-spin multiexciton states with surprisingly long lifetimes provides new opportunities for engineering singlet fission, which may also provide an intriguing route to quantum information and spintronic applications.

Strongly exchange-coupled triplet pairs in an organic semiconductor
Experiments show how molecular structure affects the interaction and dynamics of the triplet exciton pairs produced when an excited singlet exciton decays via singlet fission — a process that could be harnessed for optoelectronic applications.

Gating a single-molecule transistor with individual atoms
Transistors rely on electrical gates to control conductance but this is challenging on the atomic-scale. It is now shown that individual charged atoms can be used to electrostatically gate a single-molecule transistor with sub-ångström precision.

Many-body transitions in a single molecule visualized by scanning tunnelling microscopy
A single-particle model is usually used to interpret the tunnelling spectra of molecules on surfaces, but scanning tunnelling microscopy now shows that many-body effects can occur in a single molecule.

Spin dynamics of molecular nanomagnets unravelled at atomic scale by four-dimensional inelastic neutron scattering
Understanding the spin dynamics in magnetic nanostructures is important for spintronics, but so far it has been impossible to probe the spin dynamics directly. A neutron-scattering technique providing direct information about dynamical two-spin correlations in a molecular nanomagnet has now been demonstrated.

Multiscale photosynthetic and biomimetic excitation energy transfer
There is growing evidence that quantum coherence enhances energy transfer through individual photosynthetic light-harvesting protein complexes. This idea is now extended to complicated networks of such proteins and chemical reaction centres. A mathematical analysis reveals that coherence lengths up to 5 nm are possible.
