Analysis of Molecular Properties of Hole Transport Molecules Using Molecular Orbital Theory
Abstract:Polarizabilities and dipole moments of the existing hole transport molecules with different mobility were measured. The zero-field mobility determined by TOF technique correlated with dipole moments and polarizabilities. These results suggested that smaller dipole moment and larger polarizability of hole transport molecules are preferable properties for hole transport. Polarizabilities and dipole moments of the existing hole transport molecules were also calculated using semiempirical molecular orbital theory based on modified neglect of diatomic overlap (MNDO). The calculated polarizabilities and dipole moments strongly correlated with observed values. The fact implies that the calculated polarizability and the calculated dipole moment are good indices to develop new high mobility hole transport molecules. Semiempirical molecular orbital calculations were also applied to design new high mobility hole transport molecules.

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.
