    • note
    • The previous support of one of the authors (C.S.F.) for the dimol mechanism (ref 9) was due to the following: (a) the dimol emission wavelength corresponds very well with the absorption maxima of the most strongly emitting dyes and (b) the published triplet energy of Pc (ref 26) was too high for efficient energy transfer from singlet oxygen and because naphthalocyanines, which do have triplet energies in the right range, absorb well to the red of the phthalocyanines. The second argument has become invalidated because of the unexpectedly low energy of the triplet Pc as well as our latest results on the kinetic behavior of the SOSDF intermediate.

    • We originally felt that the exciplex mechanism was unlikely because the luminescence should saturate when the quenching of singlet oxygen by the Pc was complete, which it does not.
