    • In an effort to observe a "normal" solvent effect we examined also triphenylamine, which is a better donor than triethylamine (Table 2). However, the solvent effect for this better amine donor was very similar as for triethylamine. Although this result may be in part related to the increase in molecular size of triphenylamine, which would tend to balance the donor strength effect in Equation (1), a C value could not be estimated. The UHF-PM3 calculation does not produce minimum exciplex structures in the case of aromatic amines, which differ from aliphatic amines in that they act as "π" rather than "n" donors (cf. P. Jacques, X. Allonas, Chem. Phys. Lett. 1995, 233, 533-537).
