Beschreibung
Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a charge transport material that has high chemical stability and a high T1(minimum excitation triplet energy) and an organic EL element that uses the charge transport material and has a high efficiency, a low drive voltage, high drive durability and a low voltage rising rate during drive. SOLUTION: The charge transport material, for example, a compound represented by the formula, has a specific structure in which an electron transport part and a hole-transport part are connected through a silicon atom.
