Appl. No.:

10/771040

Inventors:

Frank Uckert - Santa Barbara CA, US
Howard Simmons - Wilmington DE, US

International Classification:

B32B009/00

US Classification:

428/690000

Abstract:

Polymeric compositions are provided comprising aromatic monomeric units selected from fluorene, spirofluorene, and bridged biphenyl, wherein the polymeric composition has at least two different substituents selected from alkyl, heteroalkyl, alkenyl, heteroalkenyl, alkynyl, heteroalkynyl, aryl, heteroaryl, arylalkyl, and heteroarylalkyl. The variation of substituents alters the morphology of invention polymeric compositions relative to polymers that lack variation of substituents. When used as an active layer(s) in electroluminescent (EL) devices, the altered morphology results in EL layers with improved efficiency, which in turn results in more efficient EL devices. The polymeric compositions of the invention also have increased solubility in solvents and better film-forming properties.

International Classification:

C08G061/00

US Classification:

528/004000, 528/397000, 528/422000

Abstract:

Polymeric compositions are provided comprising a first plurality of first monomeric units comprising an aromatic group with at least one substituent selected from alkyl, heteroalkyl, alkenyl, heteroalkenyl, alkynyl, heteroalkynyl, aryl, arylalkyl, heteroaryl, heteroarylalkyl, and amino, and a second plurality of second multi-functional monomeric units, wherein each multi-functional monomeric unit is capable of forming a branching point in the polymeric composition, thereby resulting in a branched material. Invention compositions therefore have an altered morphology relative to similar non-branched materials. When used to form an EL layer within an EL device, this altered morphology results in EL layers with improved efficiency, which in turn results in more efficient EL devices.
