N2 - Irradiation of azaxanthone in the presence of colloidal magnetite nanoparticles gives rise to the generation of the corresponding azaxanthone triplet, whose lifetime is influenced by internal magnetic field effects. In contrast, covalent tethering between magnetite and azaxanthone promotes photoinduced electron transfer leading to the observation of azaxanthone radical anion.
