ABSTRACT:
Organometallic compounds comprising an emissive core and one or more poly-phenylene branches linked to the emissive core. Host moieties are provided as pendant groups on the branches. In some cases, the poly-phenylene chain is linked in meta configuration to reduce π-conjugation in the chain. Suitable host moieties for use in the organometallic compound include those that contain carbazole or triphenylene structures. The quantity and types of host moieties on the organometallic compound may be varied to tune the molecular weight ratio of the host moieties relative to the emissive core. In some cases, the organometallic compound is sufficiently soluble in organic solvents to permit solution processing. Also provided are organic electronic devices comprising organometallic compounds of the present invention and methods for making an organic electronic device using organometallic compounds of the present invention.
