The title compound, C(33)H(30)N(2), has an E configuration 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 inter-molecular π-π inter-actions (3.510 Å) between the two fluorene rings and some C-H⋯π inter-actions.
