Claims9
A compound having Formula I
- wherein:
- Ar1-Ar6 are the same or different and are selected from the group consisting of hydrocarbon aryl groups, heteroaryl groups, and substituted derivatives thereof;
- a and b are the same or different and are 0 or 1;
- m and n are 1;
- and
- Core is Formula IB or Formula IC
- where:
- Y is the same or different at each occurrence and is selected from the group consisting of O, S, Se, Te, NR2, CR3R4, and SiR5R6;
- R2 is the same or different at each occurrence and is selected from the group consisting of alkyl, hydrocarbon aryl, heteroaryl, and substituted derivatives thereof;
- R3-R6 are the same or different at each occurrence and are selected from the group consisting of alkyl, silyl, germyl, hydrocarbon aryl, heteroaryl, and substituted derivatives thereof, where R3 and R4 and/or R5 and R6 can be joined to form a cyclic group selected from the group consisting of cycloalkyl, silacycloalkyl, spirofluorenyl, silaspirofluorenyl, or a substituted derivative thereof;
- a1 and b1 are the same or different and are 0 or 1;
- a double dashed line between two rings indicates that the rings are fused together in any orientation;
- * indicates a point of attachment in the identified formula;
- and
- # and ## represent no bond or a point of attachment in the identified formula, such that when a1=0 then # is a point of attachment, when a1=1 then # is no bond, when b1=0 then ## is a point of attachment, and when b1=1 then ## is no bond;
- and further wherein the Core may have one or more substituents selected from the group consisting of D, alkyl, silyl, germyl, hydrocarbon aryl, heteroaryl, deuterated alkyl, deuterated silyl, deuterated germyl, deuterated hydrocarbon aryl, and deuterated heteroaryl.
