摘要
An electroluminescent device comprising: - a first electrode for injection of positive charge carriers; - a second electrode for injection of negative charge carriers; and - an electroluminescent layer located between the first and second electrodes comprising a host material and a metal complex, wherein the host material comprises a polymer having a first repeat unit of formula (I): wherein each Ar is the same or different and independently represents an optionally substituted aryl or heteroaryl and any two Ar groups may be directly linked by a single bond.
