Substituent effects in soluble phthalocyaninatoiron(II) complexes

Synthesis, structure and properties of coordination compounds of iron phthalocyanines and their analogues

“…When eight electron-donating alkoxy groups are introduced into PcFe at positions adjacent to the macrocycle (at positions 1 and 4), the central iron atom is initially subjected to electrochemical oxidation, whereas the phthalocyanine ligands are oxidised in the complexes containing other substituents in the macrocycle. 109…”

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...…”

Synthesis of a Bisphthalocyanine and Its Nonlinear Optical Properties

“…The binuclear complex displayed a positive nonlinear absorption coefficient. It is found that the linear optical properties were little changed but the optical limiting effectiveness of the binuclear fused phthalocyanine 1 is lower relative to tBu 4 The versatility of Pc synthetic organic chemistry [21,22] has led to a large variety of Pc structures differing in the number, nature and position of peripheral substituents, [23][24][25][26][27] with various coordinating central atoms, [17] axial ligands, [28,29] and with a variable number of linkages between Pc rings in oligomeric [30,31] or polymeric species. [32] Among the many possibilities for varying the Pc structure, the expansion of the π-electron system through the synthesis of naphthalocyanines (Ncs) is the most common.…”
