Patent
·
OSTI ID:1371752
Optoelectronic devices with enhanced internal outcoupling include a substrate, an anode, a cathode, an electroluminescent layer, and electron transporting layer comprising a fluoro compound of formula I (Ar.sup.2).sub.n--Ar.sup.1--(Ar.sup.2).sub.n I wherein Ar.sup.1 is C.sub.5-C.sub.40 aryl, C.sub.5-C.sub.40 substituted aryl, C.sub.5-C.sub.40 heteroaryl, or C.sub.5-C.sub.40 substituted heteroaryl; Ar.sup.2 is, independently at each occurrence, fluoro- or fluoroalkyl-substituted C.sub.5-40 heteroaryl; and n is 1, 2, or 3.
