In the field of Quantum Information Technologies (QIT), organic materials are still rare. One promising family of materials are photoexcited chromophore?radical systems which, based on their properties, can be seen as surrogates to NV^– centers. In their latest contribution in the field, a collaboration between researchers at the University of Freiburg and the ICS has achieved quantum coherence at room temperature – a world first for photo-induced systems. They studied a series of perylene diimide (PDI)-TEMPO dyads, notably exploring the role of isotope labelling and the influence of a rigid polymeric matrix. This work has been published in the Journal of the American Chemical Society.
