Abstract
An electroluminescent device containing an anode, an organic electroluminescent element, and a cathode wherein the electroluminescent element contains, for example, a fluorescent hydrocarbon component of Formula (I) wherein R1 and R2 are substituents, which are selected from the group consisting of hydrogen, an alkyl, an alicyclic alkyl, an alkoxy, a halogen, and a cyano; Ar1 and Ar2 are each independently an aromatic component or an aryl group comprised of a from about 4 to about 15 conjugate-bonded or fused benzene rings.
