摘要

An optoelectronic device comprises a cathode; an electron-transporting layer comprising a compound of formula I; formula I a light emitting-layer, and an anode; wherein R1 and R2 are independently at each occurrence, hydrogen, a C rC2U aliphatic radical a CyC2U aromatic radical or a d~ C-JO cycloaliphatic radical; R3 is H or alky]; a and b are, independently at each occurrence 0, or an integer ranging from 1 to 3; n is 2 or 3; and Ar is an aryl.
