A compound of Formula (I):

• wherein:
• A is selected from CN, aryl that is substituted with at least one cyano, and a group represented by Formula (III):
• wherein:
• one of X1, X2 and X3 is N,
• the other two of X1, X2 and X3 are independently N or C(R13),
• R11, R12 and R13 are independently selected from hydrogen, deuterium, halogen, cyano, substituted or unsubstituted alkyl, substituted or unsubstituted alkoxy, substituted or unsubstituted aryl, substituted or unsubstituted aryloxy, substituted or unsubstituted heteroaryl, substituted or unsubstituted heteroaryloxy, and silyl, and
• * represents a point of attachment to Formula (I);
• and
• D1, D2 and D3 are independently selected from substituted or unsubstituted 1-carbazolyl, substituted or unsubstituted 2-carbazolyl, substituted or unsubstituted 3-carbazolyl, substituted or unsubstituted 4-carbazolyl, and group represented by Formula (II):
• wherein:
• R1, R2, R3, R4, R5, R6, R7 and R8 are independently selected from hydrogen, deuterium, substituted or unsubstituted alkyl, substituted or unsubstituted alkoxy, substituted or unsubstituted amino, substituted or unsubstituted aryl, substituted or unsubstituted aryloxy, substituted or unsubstituted heteroaryl, substituted or unsubstituted heteroaryloxy, and silyl;
• or two or more instances of R1, R2, R3, R4, R5, R6, R7 and R8 taken together can form a ring system, or R5 and R6 taken together can form single bond, and
• L1 is selected from single bond, substituted or unsubstituted arylene, and substituted or unsubstituted heteroarylene.
