NOVELTY - An amine compound (I), is new.    USE - New amine compound is used as hole-transport material, hole injection material and light emission host material for organic electroluminescent element (all claimed). Uses include but are not limited to photoelectric conversion element, solar cell, image sensor, illumination, and display of television and mobile telephone.    ADVANTAGE - The amine compound has high glass transistion temperature. The organic electroluminescent element containing layer including amine compound has low drive voltage and high power efficiency.
