ABSTRACT:
This invention is about anthracene, at least one having silyl substituted group on ring 9 and 10, the anthracene can be a organic light emitting diodes (OLED) material and used for organic electroluminescent device.wherein X is an triarylsilyl group having 6 to 20 carbon atoms, an trialkylsilyl group having 1 to 12 carbon atoms, a substituted or unsubstituted aryl group having 6 to 20 carbon atoms, a substituted or unsubstituted heteroaryl group having 2 to 20 carbon atoms, or a substituted or unsubstituted alkyl group having 1 to 12 carbon atoms. R1and R2is independently a hydrogen, halogen, or a substituted or unsubstituted alkyl group having 1 to 12 carbon atoms. R3to R5is independently a substituted or unsubstituted aryl group having 6 to 20 carbon atoms, or a substituted or unsubstituted alkyl group having 1 to 12 carbon atoms.
