Abstract
The fundamental properties of azaporphyrins can be modulated over a wide range by changing the number of meso‐nitrogen atoms. Reported herein are the first examples of 5,10,15,20‐tetraaryl‐5‐azaporphyrinium (MTAMAP) salts, which were prepared via metal‐templated cyclization of the corresponding zinc(II) and copper(II) complexes of 10‐aryl‐1‐chloro‐19‐benzoyl‐5,15‐dimesityl‐10‐azabiladiene‐ac. The inclusion of one meso‐nitrogen atom in the 5,10,15,20‐tetraarylporphyrin skeleton considerably changes the redox and optical properties as well as the degree of aromaticity of the porphyrin ring. The present findings suggest that MTAMAP salts would be promising scaffolds for the development of new azaporphyrin‐based ionic fluorophores and photosensitizers. [ABSTRACT FROM AUTHOR]
