A Synthetic Strategy for Cofacial Porphyrin‐Based Homo‐ and Heterobimetallic Complexes

We present a straightforward and generally applicable synthesis route for cofacially linked homo- heterobimetallic porphyrin complexes. The protocol allows the of unsymmetrical aryl-based meso-meso as well β-meso-linked porphyrins. Our method significantly increases overall yield published compound known o-phenylene-bisporphyrin (OBBP) by factor 6.8. Besides 16 novel homobimetallic complexes containing MnIII, FeIII, NiII, CuII, ZnII, PdII, we achieved first single-crystal X-ray structure an cofacial benzene-linked dimer both planar-chiral enantiomers NiII2 complex. Additionally, this new methodology access to such FeIII-NiII carbon monoxide dehydrogenase active site analogue. isolated species were investigated various techniques, including ion mobility spectrometry, DFT calculations, UV/Vis spectroscopy. This allowed us probe influence interplane distance on Soret band splitting.
