Abstract:
This minireview deals with the phenomenon of room-temperature phosphorescence induced by aggregation or crystallisation. Recent achievements, as well as novel classes of these unique luminophores, are put in to focus. In this fashion, different compounds, which reveal delayed fluorescence or phosphorescence upon fixation in a crystal lattice or within aggregates are described. Furthermore, the photophysical properties, the origin of the long-lived triplet states, and the possible applications of these fascinating classes of molecules are also discussed. To conclude, a short overview about the state of art in the field of pure organic phosphors at room temperature is presented.
