Cocrystalline Mixtures of Titanyl Fluorophthalocyanine and Unsubstituted Titanyl Phthalocyanine: The Mechanical Amorphization Process, Its Characterization, and Conditions for Cocrystallization
Abstract:Cocrystalline mixtures of titanyl fluorophthalocyanine (TiOFPc) and unsubstituted titanyl phthalocyanine (TiOPc) have been reported. Their preparation method involves a mechanical amorphization step (dry milling), followed by “re-crystallization” with an organic solvent, having a hydrogen bonding parameter γc lower than 9.0.
In this presentation, we will discuss the importance of the purity of the TiOPc for control of the mechanical amorphization process, as well as facilitation of cocrystallization. A novel two-step milling procedure, thermal characterization methods of amorphicity, and mixture composition will be introduced.

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.
