NEW IMIDAZOLE DERIVATIVES AND ORGANIC ELECTRONIC DEVICE USING THE SAME

摘要

A novel imidazole derivative, and an organic electronic device using the derivative are provided to improve efficiency, lifetime and stability and to lower driving voltage. An imidazole derivative is represented by the formula 1, wherein R1 and R2 are identical or different each other and are independently selected from the group consisting of a C6~C40 aryl group, a C5~C40 heteroaryl group and an amino group; at least one of R3 ~ R10 is a group represented by the formula 2 or the formula 3.
