Biomimetic MOF: Extremely stable MOFs with different open metal sites and ultra‐large 1D channels, PCN‐222 (Fe, Mn, Co, Ni, Cu, and Zn), have been assembled with eight‐connected Zr6 clusters and redox‐active metalloporphyrin motifs. PCN‐222(Fe) shows peroxidase‐like activity in aqueous solution, exhibiting highly effective biomimetic oxidation on a number of substrates.

Carboxylic ester and amide-substituted analogues of [5,10.15.20-tetrakis(4-carboxyphenyl)-porphyrinato]manganese(Ill) chloride (MnTBAP) were synthesized and assayed as potential superoxide dismutase (SOD) mimetics. The tetraester analogues 4a and 4b were found to have comparable SOD activity to the known SOD mimetic MnTBAP, while amides 4c-4e exhibited reduced SOD activity, In the substituted methyl benzoate;acid and disubstituted porphyrin series. analogues 12c, 12f and 12m were found to have comparable to improved SOD activity relative to MnTBAP and analogues 12j, 13a, and 13d exhibited improved activity in both the SOD and thiobarbituric acid reactive species (TBARS) assays relative to MnTBAP.
