In collaboration with collegues from the Cavendish Laboratory at the University of Cambridge as well as from the University of Kentucky we have published an article on singlet fission in organic semiconductors in Nature Physics. In this paper we report the observation of weakly and strongly coupled pairs of triplet excitons involved in the singlet fission process. We could identify these excitations by means of time-resolved Electron Paramagnetic Resonance (EPR) spectroscopy. Our work is highlighted by a "News and Views"-Article by Prof. Wasielewski published in the same issue of Nature Physics.
