-[PG′]< wherein Sp is a divalent organic spacer, PG′ is a group derived from a polymerisable group, and x10 is 0 or 1, with substituents and spacer as defined in claim
1.
Further disclosed are some novel polymers of this class as well as monomers for their preparation. The homopolymers are advantageously used as a host material in devices further comprising a luminiscent component, which is usually selected from phosphorescent metal complexes and fluorescent dopants.
本发明揭示了一种电致发光材料,包括基于公式(I)的重复结构单元的同聚物,其中R9,R9',R9'',R11,R13,R14,R11',R13',R14'独立地为H或有机取代基,其中至少一个R9,R9',R9'',R11,R13,R14,R11',R13',R14'包括公式—(Sp)x10-[PG']<的基团R10,其中Sp是二价有机间隔物,PG'是由可聚合基团衍生的基团,x10为0或1,取代基和间隔物如权利要求1所定义。此外,还揭示了该类新型聚合物以及用于其制备的单体。这些同聚物优选用作器件中的基材料,该器件还包括一种发光组分,通常选择自磷光金属配合物和荧光掺杂剂。
