Abstract:
Novel phosphorescent tetradentate platinum (II) compounds comprising a twisted aryl group are provided. Also provided are novel phosphorescent tetradentate platinum (II) compounds comprising an imidazo[1,2-f]phenanthridine moiety. The compounds may be used in organic light emitting devices to provide improved device efficiency, line shape and lifetime.

Claim (Index 1):
A compound having the formula: wherein A and B are independently selected from the group consisting of a 5-membered or 6-membered carbocyclic or heterocyclic ring; wherein A-B connects to Pt through one covalent bond and one coordination bond; wherein Y is selected from the group consisting of BR, NR, PR, O, S, Se, C\u2550O, S\u2550O, SO 2 , CRR\u2032, SiRR\u2032, and GeRR\u2032; wherein R and R\u2032 are independently selected from the group consisting of hydrogen, deuterium, halide, alkyl, cycloalkyl, heteroalkyl, arylalkyl, alkoxy, aryloxy, amino, silyl, alkenyl, cycloalkenyl, heteroalkenyl, alkynyl, aryl, heteroaryl, acyl, carbonyl, carboxylic acids, ester, nitrile, isonitrile, sulfanyl, sulfinyl, sulfonyl, phosphino, and combinations thereof; wherein R 3  may represent mono, di, or tri substitutions; wherein R 1  may represent a mono substitution: wherein R 1 , R 2 , and R 3  are independently selected from the group consisting of hydrogen, deuterium, halide, alkyl, cycloalkyl, heteroalkyl, arylalkyl, alkoxy, aryloxy, amino, silyl, alkenyl, cycloalkenyl, heteroalkenyl, alkynyl, aryl, heteroaryl, acyl, carbonyl, carboxylic acids, ester, nitrile, isonitrile, sulfanyl, sulfinyl, sulfonyl, phosphino, and combinations thereof; wherein two adjacent substituents of R 1 , R 2 , and R 3  are optionally joined to form a fused ring; wherein at least one of R 1  and R 2  is: wherein R\u2032 1  and R\u2032 2  are independently selected from the group consisting of hydrogen, deuterium, halide, alkyl, cycloalkyl, heteroalkyl, arylalkyl, alkoxy, aryloxy, amino, silyl, alkenyl, cycloalkenyl, heteroalkenyl, alkynyl, aryl, heteroaryl, acyl, carbonyl, carboxylic acids, ester, nitrile, isonitrile, sulfanyl, sulfinyl, sulfonyl, phosphino, and combinations thereof; wherein at least one of R\u2032 1  and R\u2032 2  is not hydrogen or deuterium; and wherein C is a 5-membered or 6-membered carbocyclic or heterocyclic ring that is optionally further substituted.
