A phenazasiline 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. In Formula I, 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. L1 may be linked with other ligands.
描述了一种包含苯肼基化合物的化合物,以及包括该化合物的装置和配方。该化合物包括一个配体L1,包括:其中E1为N,E2为Si,R4和R5代表单、双、三、四取代或不取代;其中R1、R2、R3、R4和R5各自独立地选自氢、氘、卤素、烷基、环烷基、杂基烷基、芳基烷基、烷氧基、芳氧基、氨基、硅基、烯基、环烯基、杂基烯基、炔基、芳基、杂芳基、酰基、羰基、羧酸、酯、腈、异腈、烷硫基、亚砜基、磺酰基、膦基和它们的组合,任意相邻的R1、R2、R3、R4和R5可以选择连接以形成环,该环可以进一步取代。在式I中,L1与原子量大于40的金属M配位,前提是金属M不与E1和E2形成键。L1可以与其他配体连接。
