    • 3, such a folded conformation of Zn1 would not be broken to the extent as shown in Figure 1d. However, it is reasonable to assume that the stability of three possible dimers, Zn1·Zn1, Zn1·13, and 13·13, are comparable and formed in comparable yields.

    • assoc of dimer Zn1·Zn1 with UV-vis or the fluorescent dilution method (ref 25) did not succeed, possibly due to the π∠π stacking between the porphyrin units and the hydrogen-binding moiety.

    • 3 induced a ca. 1.8 ppm downshifting for the H-1 signal of Zn1, indicating that a significant corporative effect exists for the formation of the complexes between dimeric receptor Zn1·Zn1 and dipyridyl molecules 14-17.

    • note
    • The VPO investigations for the termolecular species (Zn1· Zn1)· 14-17 did not provide useful information because of the small change of their average molecular masses relative to that of dimer Zn1·Zn1.
