1. A compound comprising a structure of Formula I, wherein Yi is, and Yj is, wherein:
RA, RB, RC, and RD each independently represents zero, mono, di-substitution or the maximum allowable substitution;
each RA, RB, RC, and RD is independently a hydrogen or a substituent selected from the group consisting of deuterium, halogen, alkyl, cycloalkyl, heteroalkyl, heterocycloalkyl, boryl, arylalkyl, alkoxy, aryloxy, amino, silyl, alkenyl, cycloalkenyl, heteroalkenyl, alkynyl, aryl, heteroaryl, acyl, carboxylic acid, ether, ester, nitrile, isonitrile, sulfanyl, sulfinyl, sulfonyl, phosphino, and combinations thereof;
at least one of RA, RB, RC, and RD comprises a carbazole moiety;
each of X1-X16 is independently C or N;
any two of RA, RB, RC, and RD can be joined or fused together to form a ring; and
wherein Yi is selected from the group consisting of:, wherein X17-X32 are each independently C or N;
RE, RF, RG, and RH each independently represents zero, mono, di-substitution or the maximum allowable substitution;
each RE, RF, RG, and RH is independently a hydrogen or a substituent selected from the group consisting of deuterium, halogen, alkyl, cycloalkyl, heteroalkyl, heterocycloalkyl, boryl, arylalkyl, alkoxy, aryloxy, amino, silyl, alkenyl, cycloalkenyl, heteroalkenyl, alkynyl, aryl, heteroaryl, acyl, carboxylic acid, ether, ester, nitrile, isonitrile, sulfanyl, sulfinyl, sulfonyl, phosphino, and combinations thereof; and
any two of RE, RF, RG, and RH can be joined or fused together to form a ring.
