description In the title compound, C(40)H(44)O(3), the fluorene ring system is essentially planar, with a maximum deviation of 0.075 (3) Å, and forms dihedral angles of 70.62 (8) and 70.31 (8)° with the mean planes of the central benzene ring and the meth­oxy­phenyl ring, respectively. Both the hexyl side chains have different conformations, i.e. an anti–gauche–anti–gauche conformation with C—C—C—C torsion angles of −169.3 (2), 74.2 (4), −178.0 (3) and −76.0 (6)° for one hexyl side chain and an anti–anti–anti–gauche conformation with C—C—C—C torsion angles of −177.9 (2), −176.5 (3), 171.7 (4) and 80.4 (9)° for the other. Four C atoms in one and two C atoms in the other hexyl side chains are each disordered over two sets of sites, with occupancy factors of 0.761 (3):0.239 (3) and 0.660 (6):0.340 (6). In the crystal, mol­ecules are via pairs of C—H⋯O hydrogen bonds, forming inversion dimers and resulting in R (2) (2)(28) graph-set motifs.
