  • 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.

  • A molecular design strategy for reducing the vibration-induced non-radiative losses in emissive organic semiconductors is realized by decoupling excitons from high-frequency vibrations.

  • Neutral π-radicals are potential emitters for optoelectronic devices due to the absence of energetically low-lying non-emissive states. Here, the authors report mesityl-substituted tris(2,4,6-trichlorophenyl)methyl radicals and achieve maximum device efficiency of 28% at a wavelength of 689 nm.

  • 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.
