Since the sulfonic acid ester compound represented by the formula (1) has high stability and high solubility in a wide range of organic solvents, it is easy to form a uniform solution and is applied to an OLED element. In this case, it is possible to realize excellent device characteristics, and it is suitable as an electron accepting substance or a thermal acid generator. (Wherein A represents a substituted or unsubstituted monovalent hydrocarbon group, X represents a substituted or unsubstituted divalent hydrocarbon group, Y represents O, S, or a substituted or unsubstituted divalent amino group. Z represents a hydrogen atom or a substituted or unsubstituted monovalent hydrocarbon group.) |
