O2 Activation at an Enzymatic Diiron Site: Bridging Ligand Substitutions Alter Diferric‐(Hydro)peroxo States

Angewandte Chemie International Edition, Volume 65, Issue 5, 28 January 2026.
Substituting the bridging carboxylates in diFe sulerythrin shifts the bridging ligand coordination from 1,3‐carboxylate to 1,1‐carboxylate, yielding all three diferrous bridging motifs in one protein. This shortens the Fe–Fe distance and increases reactivity with O2.

Path Selective Photoinduced Energy and Electron Transfer in a Bis(acridinium‐Zn(II) Porphyrin)‐tetrapyridyl Porphyrin Host‐Guest Complex

Chemistry – A European Journal, Volume 32, Issue 4, 23 January 2026.
Tuning unusual energy and eT processes in a bis(acridinium‐Zn(II) porphyrin)‐tetrapyridyl porphyrin host‐guest complex. Abstract The 1:1 complex of a bis(acridinium‐Zn(II)porphyrin) host and a tetrapyridyl free‐base porphyrin guest shows a remarkable interplay of energy and electron transfer (eT) processes, finely tuned by the solvent polarity or the ...
