Expanded porphyrins can be considered as suitable and adjustable macrocyclic frameworks for the construction of binuclear or polynuclear coordination compounds.¹ It can be expected that a multifunctional expanded porphyrin structure will enforce structurally unique coordination motifs and provide models for bimetallic metalloenzymes. Significantly, two adjacent, possibly cooperating, metal ions are in a position to prefer some unknown reaction routes that could be exploited in catalytic processes. Representative examples of such coordination chemistry have been demonstrated by amethyrins,² accordion porphyrins,³ N-confused hexaphyrins,⁴ calix[4]pyrrole Schiff base macrocycles,⁵ rubyrins,⁶ structural analogues of Pac-Man porphyrins,⁷ and other macrocycles containing a pyrrolic unit.⁸ Bimetallic complexes were also obtained for octaphyrins,⁹ and these are the primary topic of this Highlight.¹⁰–¹⁴
