Tetrazine-bridged phthalocyaninato-metal complexes as semiconducting material

Phthalocyanoiron complex with bridged ligands. Electronic structure of monomers and polymers

“…In Table VII, we have summarized the results for all polymers including experimental measures 8–27. The metallomacrocycle polymers with bridged ligands showed semiconducting properties in agreement with the experimental measurements of energy gap.…”

“…Metallophthalocyanines have been mainly investigated as part of efforts to construct new types of low‐dimensional compounds 15–27. The central metal (M) and the bridging ligand can be changed systematically.…”

Ruthenium phthalocyanine and naphthalocyanine complexes: Synthesis, properties and applications

“…Alternative routes into pure ruthenium phthalocyanine by sublimation of "crude PcRu" [34], and by thermal displacement of pyridine ligands [34,35] and isoquinoline ligands [35,36] Ruthenium phthalocyanine reacts with pyridine, methyl-, fluoro-, and chloro-pyridines to form the corresponding bis-axially substituted complexes [38,39] [32,41]. Other monomeric complexes of the potentially bridging ligands pyrazine (including substituted pyrazines), 4,4-bipyridine, pyridazine, 3,6-dimethylpyridazine, pyrimidine, s-tetrazine, and 3,6-dimethyl-s-tetrazine were also prepared by reaction of the ligand with ruthenium phthalocyanine [32,42,43]. Sterically hindered pyrazine derivatives, e.g.…”

Application of Lever’s EL Parameter Scale toward Fe(II)/Fe(III) versus Pc(2-)/Pc(1-) Oxidation Process Crossover Point in Axially Coordinated Iron(II) Phthalocyanine Complexes

“…In light of Lever’s work and the considerable academic and industrial interest surrounding iron phthalocyanine (PcFe II ) derivatives, − this work focuses on expanding the already rich chemistry of these complexes. Indeed, iron phthalocyanine complexes have been studied as catalysts for C–H bond activation, − electrocatalysts for the oxygen reduction reaction, − active components for catalytic cancer therapy, , platforms for optical detection of small molecules, − and composite materials for electrochemical detection of biologically relevant species. − The axial coordination of nitrogen bases, − phosphines and phosphites, − nitroso compounds, sulfoxides and sulfides, − carbon monoxide, − and isonitriles − to iron­(II) phthalocyanine was studied by UV–visible, NMR, and Mössbauer spectroscopies as well as by crystallography. Based on early electrochemical, spectroelectrochemical, chemical, , and photochemical oxidation data, it was always assumed that the highest occupied m...…”
