- wherein:
- each of R1, R2, R3, R4, R5, R6, R7, R8, R9, R10, R11 and R12 is independently selected from the group consisting of hydrogen atoms, halogen atoms, hydroxyl groups, cyano groups, substituted and unsubstituted C1-C30 alkyl groups, substituted and unsubstituted C1-C30 alkoxy groups, substituted and unsubstituted C1-C30 acyl groups, substituted and unsubstituted C2-C30 alkenyl groups, substituted and unsubstituted C2-C30 alkynyl groups, substituted and unsubstituted C6-C30 aryl groups, and substituted and unsubstituted C3-C30 heteroaryl groups;
- at least two of R4, R5, R6 and R7 form a saturated or unsaturated ring;
- at least two of R9, R10, R11 and R12 form a saturated or unsaturated ring;
- each of L1 and L2 is independently selected from the group consisting of single bonds, substituted and unsubstituted C1-C30 alkylene groups, substituted and unsubstituted C6-C30 arylene groups, and substituted and unsubstituted C3-C30 heteroarylene groups;
- each of Ar1 and Ar2 is independently selected from the group consisting of substituted and unsubstituted C6-C30 aryl groups, and substituted and unsubstituted C3-C30 heteroaryl groups;
- each of p and q is independently an integer ranging from 1 to 5;
