Through the challenging synthesis of tetraphenylporphyrin derivatives bearing nitroxide moieties

Hirel, Catherine/0000-0002-6297-5650; LUNEAU, Dominique/0000-0002-1831-7693 Tetraphenylporphyrin derivatives a synthetic heterocycles with convenient preparation and a richness of properties which make them attractive in broad fields such as energy, life and materials sciences. Thus, in the quest for new radical architectures, tetraphenylporphyrins are prime candidates. To this end, we designed free-base tetraphenylporphyrins bearing nitronyl and imino nitroxide moieties covalently bonded to the para-position of the meso-phenyl substituent. Their detailed synthesis and characterization arc reported here.
