Structural Characterization of Y-like Titanylphthalocyanine
Abstract:Y-Titanylphthalocyanine (Y-TiOPc) is widely used as the photoconductor for laser printers. However, little is known about its crystal structure. Therefore, an attempt has been made to grow single crystals from water-containing solution on the assumption that the Y-phase includes water. An autoclave was utilized for the crystal growth so as to suppress the solvent evaporation and thus to increase the solubility of TiOPc. The single crystals have successfully been obtained, but these are found to be phase I according to the structure analysis. However, our single crystal exhibits an intense, Y-phase-like reflection around 790 nm as revealed from polarized reflection measurements on single crystals. The present fact evidently indicates that the Y-like layer of TiOPc is formed on the surface whose thickness amounts to at least 2000 Å and that the core of the single crystal is phase I. The present interpretation is also borne out by X-ray diffraction analysis on powders as well as XPS measurements monitoring O1s and Ti2P signals.

For more than 25 years, NIP has been the leading forum for discussion of advances and new directions in non-impact and digital printing technologies. A comprehensive, industry-wide conference, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems, including drop-on-demand ink jet, wide format ink jet, desktop and continuous ink jet, toner-based electrophotographic printers, production digital printing systems, and thermal printing systems, as well as the engineering capability, optimization, and science involved in these fields.
Since 2005, NIP has been held in conjunction with the Digital Fabrication Conference.
