Title:
ELECTROLUMINESCENT POLYMERS, ORGANIC EL DEVICES AND DISPLAYS
Document Type and Number:
WIPO Patent Application WO/2005/016992
Kind Code:
A1
Abstract:
Novel electroluminescent polymers which little form cohesion structure in film formation and little cause morphologic change even after film formation and which exhibit stable EL characteristics. The polymers comprise binaphthyl derivative structural units represented by the general formula (1a) and aryl structural units represented by the general formula (1b): (1a) (1b) wherein Ar is an aryl structural unit capable of forming an electroluminescent &pgr -conjugated polymer; R1, R2, R3, and R4 may each independently take various substituents; each moiety represented by both a dotted line and a solid line represents an unsaturated double bond or a saturated single bond; m and p are each independently 0 to 2; n and o are each independently 0 to 8; x is the mole fraction of the binaphthyl derivative structural units; and y is the mole fraction of the aryl structural units.
