Click chemistry is used to functionalize simple lipophilic and water-soluble molecules, a complex PEGylated phospholipid (DSPE-PEG2000), and two benzylic substrates with the 2-(hydroxyimino)aldehyde (HIA) group. To this end, two terminal alkynes bearing the HIA moiety were synthesized and coupled to different azides through copper(I)-catalyzed azide alkyne cycloaddition (CuAAC).
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.
