Novel Hole Transport Materials and their Application for Electrophotography
The synthesis of the hole transport materials was achieved via 4-step reaction sequence: N-alkylation of the carbazole, Vilsmeier reaction followed by reaction with phenylhydrazine. In the final step, the dimer is formed. The total yield of the final product from all 4 steps is ∼ 46%. The H-NMR spectra of all intermediates along with the final product is in agreement with their structures. The hole drift mobility determined by Time of Flight measurement (TOF), ionization potential and electrophotographic cycling results of these hole transport material will be described

For more than 30 years, IS&T's series of digital printing conferences have been the leading forum for discussion of advances and new directions in 2D and 3D printing technologies. A comprehensive, industry-wide conference that brings together industry and academia, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems?particularly those involved with additive manufacturing and fabrication?including bio-printing, printed electronics, page-wide, drop-on-demand, desktop and continuous ink jet, toner-based systems, and production digital printing, as well as the engineering capability, optimization, and science involved in these fields. In 2016, the conference changed its name formally to Printing for Fabrication to better reflect the content of the meeting and the evolving technology of printing.
