A phenzasilin comprising compound, and devices and formulations including the same are described. The compound includes a ligand L1 including: wherein E1 is N, E2 is Si, and R4 and R5 represent mono, di, tri, tetra substitutions or no substitution; wherein R1, R2, R3, R4, and R5 are each 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, and any two adjacent R1, R2, R3, R4, and R5, are optionally joined to form a ring, which may be further substituted; wherein L1 is coordinated to metal M, which has an atomic weight higher than 40, provided that the metal M does not form bond with E1 and E2; and wherein L1 may be linked with other ligands. |
