Abstract
Catalase activity of manganese porphyrin dimers linked by various spacer molecules reveals a remarkable relationship between Mn–Mn separation and arrangement; the highest turnover rate is observed when the two Mn ions can cooperatively interact with a H2O2 molecule in the catalyst cavity.Keywords
