ABSTRACT:
A light-emitting organic compound that is superior in electrochemical stability, chemical stability, and thermal stability is provided. The compound also, shows blue luminescence with favorable color purity, and is represented by the following general formula (1). In the formula, X1represents a silyl group in which one or more aryl groups having 5 to 10 carbon atoms are bound to silicon or an alkyl group having 1 to 4 carbon atoms. Ar1represents an unsubstituted or substituted aryl group having 5 to 15 carbon atoms. Ar2represents an aryl group having 5 to 20 carbon atoms, and may have a substituent at a site different from a binding site to Ar1.in-line-formulae description="In-line Formulae" end="lead"?X1—Ar1—Ar2 (1)in-line-formulae description="In-line Formulae" end="tail"?
