ELECTROLUMINESCENT DEVICE

摘要

A method of forming an electroluminescent device comprising the steps of: providing a substrate comprising a first electrode for Injecting charge carriers of a first type; forming an electrolumInescent layer having a surface by depositing onto the substrate a composition comprising a host material and a light-emitting dopant monomer of formula (1): A-C-(X)n wherein X represents a polymerlsable group; A represents a light-emitting group; C represents a bond or a spacer group; and n is an integer; rendering at least some of the electroluminescent layer Insoluble in a solvent by polymarlsing the monomer of formula (1); exposing the electrolumineseent layer to the solvent; and depositing a second electrode capable of injecting charge carriers of a second type over the electrolumineseent layer.
