Interactions of Solid Supports and Fluorescent Substances in Thermally Activated Delayed Fluorescence

Analytical Sciences, 1987
The effect of the solid support on thermally activated delayed fluorescece (TADF) was investigated. Comparison of the molecular structures of supports and consideration of the energy levels of the absorption band and the fluorescence, and of lifetimes of emissions allowed the postulation of certain molecular criteria for the supports of TADF.
