Patent number: 12137605
Abstract: A compound comprising a hexadentate ligand of Formula I coordinated to a metal selected from the group consisting of iridium, rhodium, and osmium; wherein rings A, B, C, D, E, and F are independently a 5-membered or 6-membered heteroaryl ring, or a 6-membered aryl ring; T1, T2, T3, T4, T5, and T6 are independently selected from C or N, wherein two to four of T1 to T6 are C, and two to four of T1 to T6 are N; Z1, Z2, Z3, and Z4 are independently selected from C or N, wherein if Z1 and Z2 are each N then T1 is a carbene carbon and two of T2 to T6 are N; Y1 and Y2 are independently selected from the group consisting of CR, SiR, B, or N; W1-W7 are independently selected from the group consisting of a direct bond, BR, BRR?, NR, PR, O, S, Se, C?X, S?O, SO2, CR, CRR?, SiRR?, GeRR?, alkyl, cycloalkyl, aryl, heteroaryl, and combinations thereof; wherein X is selected from the group consisting of O, S, Se, NR?, and CR?R??; RA to RF independently represent mono to the maximum allowable substitution, or no substitu
