Process for preparing titanyl phthalocyanine

A process for preparing titanyl phthalocyanines in one reaction reactor includes the reaction of titanium tetrachloride or titanium trichloride and o-phthalodinitrile in an organic solvent such as 1-chloronaphthalene in the presence of a molecular sieve as a promoter followed by hydrolysis resulting in titanyl phthalocyanines. The prepared titanyl phthalocyanines is usable as a high-quality charge generating material and can be used as a charge generating layer in an organic photoconductor drum.

Mu-oxo bridged heterometal compound and selective production method thereof

An object of the present invention is to provide a new μ-oxo bridged heterometal compound, which can make the photo-functional materials to have diversified properties, and a production method such that the μ-oxo bridged heterometal compound is obtained simply, selectively and with high yield. The present invention provides μ-oxo bridged heterometal compounds, NcM1-O-M2Nc, PcM1-O-M2Nc and NcM1-O-M2Pc wherein Nc represents naphthalocyanine, Pc represents phthalocyanine, M1 represents a metal atom which is able to have a valence of up to three, and M2 represents a metal atom which is able to have a valence of four or five.

Solvent Effects on Electronic States of Phthalocyanines

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.
