Abstract

This invention relates generally to norbornene-monomer, poly(norbornene)homopolymer, and poly(norbornene)copolymer compounds containing a functionalized carbazole side chain, having desirable solution processability and host characteristics. It also relates to hole transport and/or electron blocking materials, and to organic host materials for an organic luminescence layer, an OLED device, and compositions of matter which include these compounds.
