Solvent Effects on Electronic States of Phthalocyanines
Harazono, Toshie,Takagishi, Iwao
, p. 1016 - 1023 (1993)
The absorption spectra of a ?-?* transition (the Q band) of titanium(IV) oxide phthalocyaninate (TiOpc) and phthalocyanine (H2pc) were measured in various organic solvents.It has been shown that the wavelength of the ?-?* transition is dependent on 1) the permanent dipole moment of the solvent, 2) the coordination of the solvent, and 3) the dispersion force and induced dipole moment of the solvent.A single ?-?* peak and its significant red-shift in the absorption spectrum of H2pc in trifluoroacetic acid (TFA) suggested a protonation of the inner nitrogen atoms, leading to H4pc2+.TiOpc in TFA was cleaved, followed by the release of H2pc.The overall reaction was proposed to be as follows; TiOpc + 4CF3COOH Ti(CF3COO)4 + H2O + H2pc.

Page/Page column 6, (2008/06/13)
An object of the present invention is to provide a novel μ-oxo bridged heterometal phthalocyanine compound, and a production method such that the μ-oxo bridged heterometal phthalocyanine compound is obtained simply, selectively and with high yield. The μ-oxo bridged heterometal phthalocyanine compound has a structure in which the central metal atom (M1) in a metal phthalocyanine including M1 as central metal thereof is oxo-bridged with the central metal M2 in a metal phthalocyanine including M2 as central metal thereof.
Synthesis of dichloro phthalocyaninato complexes of titanium, zirconium, and hafnium
Tomachynski,Chernii,Volkov
, p. 208 - 211 (2008/10/08)
A new approach to the synthesis of dichloro phthalocyaninato complexes of titanium, zirconium, and hafnium was developed. The hydrolytic stability of the compounds synthesized was studied. All complexes were characterized by elemental analyses and IR and electronic absorption spectra.
