Title:
The phenyl and the fluorenyl substitution Feni rupee Pyrazole complex of iridium (Ir)
Document Type and Number:
Japanese Patent JP5985189
Kind Code:
B2
Abstract:
The invention is directed to a compound having the following formula:
wherein M is a metal having an atomic weight greater than 40; C-N is a substituted or unsubstituted cyclometallated ligand, and (C-N) is different from at least one other ligand attached to the metal; wherein at least one ligand functions as a phosphorescent emissive ligand in the compound at room temperature and at least one ligand does not function a phosphorescent emissive ligand in the compound at room temperature; wherein the emissive ligand in the compound at room temperature has a triplet energy corresponding to a wavelength that is at least 80 nm greater than the wavelength corresponding to the triplet energy of a ligand that is not emissive in the compound at room temperature; wherein each of R 8 and R 11 to R 14 is independently selected from hydrogen, alkyl, alkenyl, alkynyl, alkylaryl, CF 3 , NO 2 , halo, aryl, heteroaryl, substituted aryl, substituted heteroaryl, or a heterocyclic group; X is independently selected from hydrogen, alkyl, alkenyl, alkynyl, alkylaryl, CN, CF 3 , NO 2 , halo, aryl, heteroaryl, substituted aryl, substituted heteroaryl, or a heterocyclic group; Z is selected from -CH 2 -,-CRR-, wherein each R is hydrogen, alkyl, alkenyl, alkynyl, alkylaryl, CN, CF 3 , NO 2 , halo, aryl, heteroaryl, substituted aryl, substituted heteroaryl, or a heterocyclic group; and n has a value of at least 1; and m+n is the maximum number of ligands that may be attached to the metal.
