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, Ar
1
represents a substituted or unsubstituted aryl group having 6 to 10 carbon atoms in a ring. When Ar
1
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. Ar
2
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 Ar
2
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. R
1
and R
2
independently represent a hydrogen atom or an alkyl group having 1 to 4 carbon atoms.
本发明的目的是提供一种新型的氧代二唑衍生物,其通式表示为(G1),作为具有高电子传输性能的物质。在公式中,Ar1表示具有6至10个碳原子环中的取代或未取代芳基基团。当Ar1具有取代基时,取代基为具有1至4个碳原子的烷基基团或具有6至10个碳原子环中的芳基基团。Ar2表示具有6至10个碳原子环中的取代或未取代芳基基团或具有4至9个碳原子的取代或未取代杂环芳基基团。当Ar2具有取代基时,取代基为具有1至4个碳原子的烷基基团或具有6至10个碳原子环中的芳基基团。R1和R2独立地表示氢原子或具有1至4个碳原子的烷基基团。
