Tetrapyrazinoporphyrazines and their metal derivatives. Part II: Electronic structure, electrochemical, spectral, photophysical and other application related properties
Tetrapyrazinoporphyrazines (TPyzPzs), the heterocyclic azaanalogs of the phthalocyanine macrocycle, known since the 1930 s, but became an object of intensive studies in the last decades. In Part I (Coord. Chem. Rev. 2016, 309, 107–179) the synthesis of variously substituted TPyzPzs and their metal complexes as well as of their precursors was presented. In the present Part II, we consider the peculiarities of their electronic structure, electrochemical, spectral, acid–base and photophysical properties.
