Title:
CARRIER TRANSPORT POLYMER
Document Type and Number:
Japanese Patent JP3482719
Kind Code:
B2
Abstract:

PURPOSE: To obtain a carrier transport polymer which enables a carrier layer of an org. thin-film EL element to be formed by a method using a solvent and has a Tg of 120°C or higher and improved mechanical strengths by selecting a polymer having a specific structure.
CONSTITUTION: This carrier transport polymer is represented by formula I [wherein m is the degree of polymn. ; G1 is a single bond, arylene, alkylene, alkylenedioxy, or a group selected from among groups represented by formulas II; G2 is (halogenated) alkyl; G3 is H or alkyl; G4 is a group selected from among groups represented by formulas III; and G5 is 1-12C alkyl or alkoxy]. The polymer wherein G1 is p-phenylene is esp. pref. And, the polymer pref. has a wt. average mol.wt. (by GPC) of 2,000-1,000,000, can be produced by the Wittig reaction of a dicarbonyl compd. with a phosphorus ylide, Ph3P+C-H2G1C- H2P+Ph3, and can be formed into a film by spin coating or casting.
