N2 - π-Donor-polyoxyethylene-capped Zn(II)-porphyrins, 1-3, form supramolecular complexes with N,N′-dimethyl-4,4′-bipyridinium, MV2+, 4. The association constants of the resulting adducts are 8 × 104, 1 × 104, and 1 × 103 M-1, respectively. The Zn(II)-porphyrins are quenched by MV2+ by two complementary routes that include internal electron-transfer quenching in the supramolecular complexes and diffusional electron-transfer quenching of the free chromophore.
