More Information
Summary:Disclosed is a compound comprising a first ligand L_A of chemical formula I. In the L_A, ring B is a 5- or 6-membered ring. Y is O, S, NR^Y, or CR^YR^Y'. Z^1 is O, S, NR, or CRR'. X^1 is C or N. Each of R, R', R^Y, R^Y', R^A, and R^B is hydrogen or a substituent. L_A is coordinated to metal M by a dotted line. Any two of R, R', R^Y, R^Y', R^A, and R^B are connected to form a ring. However, the compound does not include chemical formula II. Herein, each of Z' and Z" is C or N. Disclosed are a combination product containing the compound, an OLED, and a consumer product. JPEGpat00216.jpg5352의 제1 리간드 LA를 포함하는 화합물이 개시된다. LA에서, 고리 B는 5원 또는 6원 고리이고; Y는 O, S, NRY 또는 CRYRY'이며; Z1은 O, S, NR 또는 CRR'이고; X1은 C 또는 N이며; 각각의 R, R', RY, RY', RA 및 RB는 수소 또는 치환기이고; LA는 점선에 의해 금속 M에 배위결합되며; R, R', RY, RY', RA 및 RB 중 임의의 2개는 연결되어 고리를 형성할 수 있고; 단, 화합물은 화학식 II JPEGpat00217.jpg5742를 포함하지 않으며, 여기서 Z' 및 Z" 각각은 C 또는 N이다. 상기 화합물을 함유하는 배합물, OLED 및 소비자 제품이 또한 개시된다.
