Electroactive polymeric arylenes and intermediates useful for making such polymers are disclosed. The present invention also provides electroactive compositions comprising the electroactive polymeric arylenes, organic electronic devices which comprise these polymers and compositions, and methods of fabricating these devices.
Organic electroluminescent compositions comprise
(a) a charge transport matrix comprising at least one electron transport material;
(b) at least one non-polymeric emissive dopant; and
(c) at least one tertiary aromatic amine selected from the group consisting of
(1) tertiary aromatic amines wherein at least one of the organic groups comprises a substituted phenyl group having an electron-donating substituent in the para-position or two independently selected electron-donating substituents in the meta-positions,
(2) tertiary aromatic amines wherein at least two of the organic groups each comprise an independently selected substituted biphenyl or substituted fluorenyl group having an electron-donating substituent in the para-position of its terminal phenyl ring, and
(3) tertiary aromatic amines wherein at least one of the organic groups comprises a fused polyaromatic group and at least one other organic group comprises a substituted biphenyl or substituted fluorenyl group having an electron-donating substituent in the para-position of its terminal phenyl ring.
