Disclosed are electroluminescent materials comprising a homopolymer based on recurring structural units of the formula (I) wherein R9, R9′ R9″, R11, R13 R14, R11′, R13′, R14′ independently are H or an organic substituent, where at least one of R9, R9′ R9″, R11, R13 R14, R11′, R13′, R14′ comprises a group R10 of the formula —(Sp)x10-[PG′]< wherein Sp is a divalent organic spacer, PG′ is a group derived from a polymerizable 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 luminescent component, which is usually selected from phosphorescent metal complexes and fluorescent dopants.
本发明涉及电致
发光材料,包括基于结构单元(I)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是双价有机间隔,PG'是从可聚合基团衍生的基团,x10为0或1,其取代基和间隔如权利要求1所定义。本发明还公开了一些新型的同类聚合物以及用于它们制备的单体。这些同聚物优选用作器件中的主体材料,该器件进一步包括通常选自荧光染料和磷光
