Patent ID: 7402345

Claim:
An organic electronic device comprising at least one layer comprising a composition of Formula I wherein: R 1 =H, F, or C n F 2n+1 ; R 2 =H, or C n F 2n+1 ; R 3 =NO 2 , Me (methyl) or NR 2 ; R=is the same or different at each occurrence and is alkyl, aryl, or adjacent R groups are alkylene or substituted alkylene and can join together to form a 5- or 6-membered ring; L′=a bidentate ligand and is not a phenylpyridine, phenylpyrimidine, or phenylquinoline; L″=a monodentate ligand, and is not a phenylpyridine, phenylpyrimidine, or phenylquinoline; m=1 or 2; y=1 or 2; z=0 or 2; and n is an integer from 1 through 20, with the proviso that the composition is charge neutral and the iridium is hexacoordinate; and wherein at least one L′ is a phosphino alkoxide ligand of Formula IV: where R 7 can be the same or different at each occurrence and is selected from H and C n (H+F) 2n+1 ; R 8 can be the same or different at each occurrence and is selected from the group of C n (H+F) 2n+1 , C 6 (H+F) 5 , C 6 H 5−n (R 9 ) n , and (CH 2 ) n C(C n (H+F) 2n+1 ) 2 OH; R 9 =CF 3 , C 2 F 5 , n-C 3 F 7 , i-C 3 F 7 , C 4 F 9 , or CF 3 SO 2 ; and q is 2 or 3 or L′ is selected from the group of ligands having structure according to Formula V: Ar[—(CH 2 ) r —Y] p Formula V wherein Ar is phenyl; Y is P(Ar) 2 ; r is 0 or an integer from 1 through 20; p is 1 or 2, wherein the carbon in one or more of the (CH 2 ) can be replaced with a heteroatom and one or more of the hydrogens in one or more of the (CH 2 ) can be replaced with D or F and wherein if m=2, then each occurrence of can be the same or different.
