    • Assuming all the parameters equal, the sensitivity of the excited state towards quenching by diffusing molecules is proportional to the excited state lifetime, and, therefore, it is four to five orders of magnitude higher for phosphorescent than for fluorescent chromophores.

    • A more rigorous proof, requiring complete spectroscopic signatures of ionic species formed as a result of the ET reaction, was left for the next stage, when the covalent assemblies are constructed from the selected chromophores.
