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.

Polymerscontaining terminal hydrogen-bonding recognition motifs based on diaminotriazine and diaminopyridine groups in their side chains for the self-assembly of appropriate receptors have been prepared by ring-opening metathesis polymerization (ROMP) of norbornenes. A new synthetic method for the preparation of norbornene monomers based on pure alkyl spacers is introduced. These monomers show unprecedented

We report novel host polymers for a high‐efficiency polymer‐based solution‐processed phosphorescentorganic light‐emitting diode with typical blue‐emitting dopant bis(4,6‐difluorophenylpyridinato‐N,C2)iridium(III) picolinate (FIrpic). The host polymers, solublepolynorbornenes with pendantcarbazolederivatives, N‐phenyl‐9H‐carbazole (P1), N‐biphenyl‐9H‐carbazole (P2), and 9,9′‐(1,3‐phenylene)bis‐9H‐carbazole

ring-opening metathesis polymerization. The polymeric materials obtained were characterized by IRspectroscopy, GPC and DSC methods, and elemental analysis. All the copolymers possess strong metal-centered photoluminescence in solution and in thin film. In the electroluminescence spectra, the emission of the europium cations is exhibited and a broad band with the maximum at 507 nm is observed, which supposedly
