The title compound, C33H30N2, has an E configuration General Wound Care - Sponge Counters at the imine double bond.The angle between the least-squares planes of the imine C=N—C group and the benzene ring of the 2,4,6-trimethylphenyl substituent is 85.38 (11)°.The crystal structure is sustained mainly by intermolecular π–π interactions (3.510 Å) between the two fluorene Fridge Roller rings and some C—H.
π interactions.
