PtII-based emitters. Time-resolved transient absorption and fluorescence up-conversion experiments complemented by quantum chemical calculations employing Kohn-Sham density functional theory and multireference configuration interaction methods as well as temperature-dependent steady-state and time-resolved luminescence studies provide a detailed picture of the excited state dynamics of 2.
