<p>PROBLEM TO BE SOLVED: To provide a silane compound further improving luminous efficiency and element life of an organic EL element.SOLUTION: There is provided a silane compound represented by the formula, where Rto Rare monovalent or bivalent substituents derived from aromatic hydrocarbon having 5 to 30 carbon atoms or a hetero aromatic ring, which are all unsubstituted or one or more of which has an alkyl group having 12 or less carbon atoms, the number of carbon of Ris more than that of Rby 4 or more, the numbers of carbon of Rand Rare 12 or less, the numbers of carbon of Rand Rare 18 or less, n is an integer of 1 to 3, the number of substituents of an alkyl group substituted by Rto Ris not over the number of hydrogen atoms of Rto R, the number of carbon atoms of Rto Ris the number of carbon atoms excluding the number of carbon atoms of the alkyl group substituted by Rto Rand the monovalent group and the bivalent group are not generated from the alkyl group substituted by Rto R.</p> |
