1. A compound having a partial structure of Formula I: wherein M is a metal with an atomic number of at least 40; wherein RA, RB, and RC are each independently 5 or 6 membered aryl or heteroaryl rings; wherein R1, R2, and R3 each independently represent no substitutions or up to the maximum available substitutions; wherein R1, R2, and R3 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, phosphine, and combinations thereof; wherein A is selected from the group consisting of hydrogen, deuterium, halide, alkyl, cycloalkyl, heteroalkyl, arylalkyl, alkoxy, aryloxy, amino, silyl, alkenyl, cycloakenyl, heteroalkenyl, alkynyl, aryl, heteroaryl, acyl, carbonyl, carboxylic acids, ester, nitrile, isonitrile, sulfanyl, sulfinyl, sulfonyl, phosphine, and combinations thereof; wherein A is optionally bonded to RA or RC to form a fused ring; wherein X1 is B, C, N, O, S or Se; wherein X2-X7 are independently B, C or N; and wherein Y1-Y2 are independently C or N. |
