The borane derivatives of this invention are suitable for luminescent materials by virtue of their high luminous efficiencies in solid states, and useful for electrophotography and as photoelectronic functional materials including nonlinear optical materials and conductive materials. The use of this borane derivative brings about an organic EL device characterized by low electricity consumption and high efficiency.
