POLYMER FOR FORMING ORGANIC ELECTROLUMINESCENT ELEMENT, POLYMER COMPOSITION FOR ORGANIC ELECTROLUMINESCENT ELEMENT AND ORGANIC ELECTROLUMINESCENT ELEMENT

摘要

PPROBLEM TO BE SOLVED: To obtain a polymer forming an organic electroluminescent emission layer having emission brightness by wet process, a composition containing the polymer and presenting an emission layer expressing strong emission brightness and an organic electroluminescent element having the emission layer expressing strong emission brightness. PSOLUTION: The polymer consists of a repeating unit expressed by structural formula (1), wherein RSP1/SP, RSP2/SPand RSP3/SPexpress each a monovalent organic group; l expresses 0-4 integer, m expresses 0-4 integer; n expresses 0-4 integer. The composition comprises a polymer component comprising the polymer and a complex component comprising a triplet luminescent metal complex compound. The organic electroluminescent element has the emission layer presenting high emission brightness formed by using the composition. PCOPYRIGHT: (C)2006,JPO&NCIPI
