Abstract

Graphical abstract: Coordination polymers (CPs) constructed from pyridyl or S-pyridyl porphyrins containing copper or zinc clusters are reported. The metal cluster has a key contribution in catechol oxidation. Abstract: Coordination Polymer-type materials obtained from the reaction of 5, 10, 15, 20-tetrakis[2, 3, 5, 6-tetrafluoro-4-(4-pyridylsulfanyl)phenyl]porphyrin (H2 P1 ) and 5, 10, 15, 20-tetrakis(4-pyridyl)porphyrin (H2 P2 ) with copper(II) and zinc(II) acetate are reported. Materials show catalytic activity for the oxidation of catechol comparable to that of the copper Porphyrin-Metal Organic Framework belonging to the same family of compounds previously reported by us. The ability of the porphyrin's tetrapyrrolic core to accommodate metal ions of varying charges seems to modulate the catalytic activity.
