摘要:
Novel benzoxazole derivatives are provided to reduce driving voltage of light-emitting elements, and to reduce power consumption of light-emitting elements, light-emitting devices, and electronic devices. A benzoxazole derivative represented by the general formula (G1) is provided. Since the benzoxazole derivative represented by the general formula (G1) has an electron-injecting property, the benzoxazole derivative can be suitably used for light-emitting elements, light-emitting devices, and electronic devices.
摘要:
An object is to provide a novel oxadiazole derivative represented by General Formula (G1) as a substance having a high electron-transport property. In the formula, Ar1 represents a substituted or unsubstituted aryl group having 6 to 10 carbon atoms in a ring. When Ar1 has a substituent, the substituent is an alkyl group having 1 to 4 carbon atoms or an aryl group having 6 to 10 carbon atoms in a ring. Ar2 represents a substituted or unsubstituted aryl group having 6 to 10 carbon atoms in a ring or a substituted or unsubstituted heteroaryl group having 4 to 9 carbon atoms. When Ar2 has a substituent, the substituent is an alkyl group having 1 to 4 carbon atoms or an aryl group having 6 to 10 carbon atoms in a ring. R1 and R2 independently represent a hydrogen atom or an alkyl group having 1 to 4 carbon atoms.
