Physicochemical characterization of subporphyrazines-lower subphthalocyanine homologues

Physicochemical characterization of boron(III) subporphyrazines (SubPzs)-lower subphthalocyanine (SubPc) homologues-has been carried out for the first time. The SubPz macrocycle can act both as an oxidizing and a reducing entity, giving rise to stable radical anion or radical cation species, respect...
