A Stable Radical Species from Facile Oxygenation of meso‐Free 5,10,20,25‐Tetrakis(pentafluorophenyl)‐Substituted [26]Hexaphyrin(1.1.1.1.1.1)

Abstract

A stable radical: The title compound 1 has been synthesized as the first example of a meso-free variant and characterized as a strongly aromatic macrocycle with a spectacles-like planar conformation. The incorporation of free meso positions is promising for the exploration of novel structural and electronic properties.
