Phenanthroline compounds and electroluminescent devices using the same

In OLEDs, improved efficiency is obtained by using compounds of formula Ar(CH=CH-R1)n wherein n is an integer from 1 to 4; Ar is a polycyclic aromatic or heteroaromatic scaffold optionally substuted with one or more alkyl or alkoxy groups; and R1 is a 5-membered heteroaryl group optionally substitut...

More Information
Summary:In OLEDs, improved efficiency is obtained by using compounds of formula Ar(CH=CH-R1)n wherein n is an integer from 1 to 4; Ar is a polycyclic aromatic or heteroaromatic scaffold optionally substuted with one or more alkyl or alkoxy groups; and R1 is a 5-membered heteroaryl group optionally substituted with methyl, methoxy, aryl or heteroaryl, or is phenyl or naphthyl optionally substituted with methyl, methoxy, trifiuoromethyl or cyano or is biphenyl or substituted biphenyl. The compounds are believed to be novel and can be made by condensing a compound of formula wherein Ar and n are as defined above with a compound of formula Ar(CH3)n R1CHO in the presence of an acid catalyst e.g. an anhydride of an organic acid.
