Abstract
Disclosed are electroluminescent materials comprising a homopolymer based on recurring structural units of the formula (I) wherein R, RR, R, RR, R, R, Rindependently are H or an organic substituent, where at least one of R, RR, R, RR, R, R, Rcomprises a group Rof the formula —(Sp)-[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. 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.
