  • Controlling electron spin states with light is vital for quantum technologies but requires electronic excitations with net spin. Now a molecular diradical with two trityl radical groups coupled via a meta-linked fluorene bridge has been developed that features luminescent singlet and triplet excitons. The spins in the ground state can be written and read using photons, giving rise to broad magnetic and microwave modulation of the photoluminescence.

  • Plant Light Harvesting complexes adjust to light conditions via a quenching mechanism involving carotenoids. The authors use computational simulations to reveal how carotenoids’ quenching capacity is tuned by conformational changes of the complex.

  • Exploiting the energy transfer between the host triplet states and spin doublet exciton states of a radical organic emitter enables near-infrared organic light-emitting diodes with an external quantum efficiency up to 9.6% at an emission wavelength of 800 nm.

  • A low singlet-triplet energy gap, necessary for delayed fluorescence organic semiconductors, results in a small radiative rate that limits performance in OLEDs. Here, the authors show that it is possible to reconcile these conflicting requirements in materials that can access both high oscillator strength intramolecular excitations and intermolecular charge transfer states.

  • A substantial pathway for energy loss in organic solar cells may be suppressed by engineering hybridization between non-fullerene acceptor triplet excitons and spin-triplet charge transfer excitons.

  • Though single-material organic solar cells are attractive for next-generation photovoltaic technologies, designing new materials with ideal properties remains a challenge. Here, the authors report the use of orientation-dependent molecular electrostatics to realise efficient homojunction devices.

  • We report organic molecules showing both efficient luminescence and near-unity generation yield of excited states with high spin multiplicity, simultaneously supporting a high efficiency of initialization, spin manipulations and light-based readout at room temperature.
