Fig. 5. UV-vis-NIR denaturation titrations of linear porphyrin oligomer complexes with templates T4 and T5 (all in CHCl3 at 298 K). The spectra shown on the left are those of the 1 : 1 complexes (black) and the end spectra of the pyridine-saturated oligomers (red). On the right the experimental (black circles) and calculated binding isotherms (red lines) are shown. All titrations were performed at least twice (see ESI, Section S1.2†).
