6. pH does not vary during the titration.
7. A closer look at the titration reported in Figure 3 shows slope changes at both the 2:4 and 4:4 ratios. However, the break points are not sharp enough to clearly state the formation of these species. On the other hand, the formation of the 2:4 species is well recognized in Figure 4.
8. 4TsTc emission quenching because AuT4 does not emit.
9. Most likely this limitation is due to the presence of an extra positive charge in the porphyrin core.
10. 4 while the distance between an axially coordinated water molecule and the porphyrin plane is about 2.5 Å.
