Nevertheless, the most astonishing results were with MeOH and CHCl3. As discussed, in MeOH, the D alone could not deprotonate in the excited-state (Fig. ). Still, in the D-B-A system of both peptide sequences, we could observe the deprotonation of the D in the fluorescence spectrum by the emergence of the peak associated with deprotonated D (Fig. and). For the (A)8 peptide, only the D-B-A configuration showed a deprotonated D species, while the D-B control did not (Fig. ), thus indicating the fundamental role of the PMF in driving the PT process for this peptide.
