SPIRO-FLUORINE-9,2'-IMIDAZOLE BASED BIPOLAR MAIN MATERIAL, SYNTHESIS METHOD THEREFOR, AND APPLICATION THEREOF

摘要

A spiro-[fluorine-9,2'-imidazole] based bipolar main material, a synthesis method therefor, and an application thereof, relating to the field of organic electronic materials. The bipolar main material has a compound having the structure of formula (I), wherein at least one of R₁-R₃ is C1-C4 alkyl or alkoxyl substituted or unsubstituted acridinyl, phenothiazinyl, carbazole, diphenylamine. The bipolar main material has higher glass-transition temperature, and therefore is beneficial to carrier injection and transport equilibration.
