NOVELTY - An imidazole derivative (I) is new.    USE - New imidazole derivative is used in organic electronic devices e.g. organic light-emitting device, organic solar cell, organophotoreceptor, and organic transistor (all claimed).    ADVANTAGE - The new imidazole derivative provides organic electronic device with excellent brightness, luminous efficiency, durability and stability, and reduced drive voltage.    DETAILED DESCRIPTION - An imidazole derivative of formula (I) is new.
