Latest Patents

Lung-Tarn Wu holds a patent for "Electrophotographic photoreceptors containing titanyl phthalocyanine." This invention discloses an ammonia-modified titanyl phthalocyanine for use in preparing the charge-generating layer of a photoreceptor. The process involves several steps, including reacting titanium tetrachloride with halogen-containing naphthalene to obtain an unmodified titanyl phthalocyanine. The unmodified titanyl phthalocyanine is then dispersed in an organic solvent and subjected to an ammonia-induced complexation-mediated crystal transformation. This transformation can be achieved by either bubbling ammonia gas through the solution or by adding an ammonia-saturated aqueous solution. The resulting ammonia-modified titanyl phthalocyanine is characterized by specific Bragg diffraction angles and vibrational absorption resonances. The photoreceptor demonstrates excellent spectral sensitivity in the near-infrared range and remarkable cyclic stability.
