Abstract: | The complexation properties of zinc 10,20-bis[5-(2,3,7,8,12,13,17,18-octaethylporphyrinate)ethynylphenyl]-5,5′,10′,15,15′,20′-hexamethylcalix[4]pyrrole toward halide ions, triethylenediamine, and 4,4′-bipyridyl were studied by spectrophotometric titration and 1H NMR spectroscopy. The influence of binding of anions (F− and Cl−) by the calix[4]pyrrole fragment of zinc calixpyrrole-bisporphyrinate on the complexation properties of its interporphyrin cavity toward the bidentate organic ligand triethylenediamine. |
