The solvent‐ and concentration‐dependent photostability of TIPS‐pentacene in solution is directly related to the efficiency of singlet‐state deactivation by a combination of pairwise interactions and quenching at low concentration. At higher concentrations, further increases in stability suggest the onset of aggregation.
