    • While this distance can appear too long with respect to the molecular structure, it should be noted that the presence of the negatively charged counterion can lower the effective charge of the cation. Indeed a fit of the spectra of 1 c can analogously be obtained by fixing the distance to 8 Å and imposing a partial positive charge of 0.7e on the ammonium moiety.

    • In other solvents fluorescence quantum yields are always lower than 1 %.

    • note
    • Calculated TPA cross sections underestimate experimental ones by a factor of about 2. This agreement is acceptable in consideration of the two-state description adopted for the chromophore and of the absence of any local field correction.
