Claim 11:
12. The compound of claim 1, wherein the at least one of R includes a polycyclic group selected from the group consisting of:
(a) a group selected from the group consisting of, wherein
X1 to X30 are independently selected from the group consisting of N and CRX, but no single 6-membered aromatic ring can have more than three N; wherein RX is selected from the group consisting of hydrogen, deuterium, halogen, alkyl, deuterated alkyl, cycloalkyl, heteroalkyl, arylalkyl, alkoxy, aryloxy, amino, silyl, alkenyl, cycloalkenyl, heteroalkenyl, alkynyl, aryl, heteroaryl, acyl, nitrile, isonitrile, sulfanyl, sulfinyl, sulfonyl, phosphino, and combinations thereof;
Y is selected from the group consisting of C and Si;
Z1 and Z2 are independently selected from the group consisting of NR, BR, N, O, S, Se, CR1R2, SiR1R2, and GeR1R2; wherein R1 and R2 are independently selected from the group consisting of deuterium, alkyl, aryl, heteroaryl, and combinations thereof; and
L1, L2, L3, and L4 are independently selected from the group consisting of O, S, BR, NR, CR1R2 and SiR1R2, wherein the at least one polycyclic group is bonded to one of T2, T3, or T4 through one of X1 to X30, one of L1 to L4, or one of Z1 and Z2;

(b), wherein
X1 to X8 are independently selected from the group consisting of N and CRX, but no single 6-membered aromatic ring can have more than three N; wherein RX is selected from the group consisting of hydrogen, deuterium, halogen, alkyl, deuterated alkyl, cycloalkyl, heteroalkyl, arylalkyl, alkoxy, aryloxy, amino, silyl, alkenyl, cycloalkenyl, heteroalkenyl, alkynyl, aryl, heteroaryl, acyl, nitrile, isonitrile, sulfanyl, sulfinyl, sulfonyl, phosphino, and combinations thereof;
the polycyclic group is bonded to one of T2, T3, or T4 through one of X1 to X8;
Z1 is selected from the group consisting of, BR, NR, O, S, Se, CR1R2, SiR1R2, and GeR1R2; provided that when Z1 is O or S, then at least one of X1 to X8 is N; and
R1 and R2 are independently selected from the group consisting of deuterium, alkyl, aryl, heteroaryl, and combinations thereof; and

(c), wherein
the polycyclic group is bonded to one of T2, T3, or T4 in Formula II through one of X1 to X8 or one of Z1 and Z2;
X1 to X8 are independently selected from the group consisting of N and CRX, but no single 6-membered aromatic ring can have more than three N; wherein RX is selected from the group consisting of hydrogen, deuterium, halogen, alkyl, deuterated alkyl, cycloalkyl, heteroalkyl, arylalkyl, alkoxy, aryloxy, amino, silyl, alkenyl, cycloalkenyl, heteroalkenyl, alkynyl, aryl, heteroaryl, acyl, nitrile, isonitrile, sulfanyl, sulfinyl, sulfonyl, phosphino, and combinations thereof;
Z1 and Z2 are independently selected from the group consisting of NR, BR, N, O, S, Se, CR1R2, SiR1R2, and GeR1R2; and
R1 and R2 are independently selected from the group consisting of deuterium, aryl, heteroaryl, and combinations thereof.
