    • 2+ salts were added to a solution of the simple dipyrrin, no spectroscopic response was observed. This result is consistent with the literature; see reference [7f]. Furthermore, Bucher's stability index also predicts a low stability for the Mg-porphyrin complex; see: in (Ed.: K. M. Smith), Elsevier, Dordrecht, .

    • This trend is opposite to what would be expected for a typical acceptor-excited PET system. Therefore, we conclude that an a-PET (a=acceptor) process does not play a significant role in regulating the excited-state behavior in this instance. When trifluoroacetic acid (TFA) was added to a solution of H-P1 in MeCN, protonation at the one of the nitrogen atoms of the 1,10-phenanthroline unit took place; see

    • On the other hand, no enhancement in the emission characteristics of the protonated form of H-P1 occurred in the visible-light region (see the Supporting Information, Figure S10). This result provides further support for the conclusion that intramolecular PET from the 1,10-phenanthroline moiety to the acceptor fluorophore (dipyrrin; acceptor-excited PET: a-PET) does not occur to an appreciable extent.
