Abstract

There is provided a charge transport material which can easily be coated to form a film, is less likely to be crystallized during or after film formation, has excellent charge transport capability, and high applicability to electronic devices. A charge transport monomer comprising conventional CBP with a specific substituent introduced thereinto is polymerized to prepare a polymer which is brought to a charge transport material comprising this polymer.
