The title compound, C37H42, is a new mesogenic compound containing the fluorene moiety. It exhibits enantiotropic nematic liquid crystalline behaviour with melting at 125 °C and isotropization at 175 °C. The crystallographically independent unit contains two molecules oriented face-to-edge with respect to each other. The two molecules have nearly the same conformation of the bis-phenyl fluorene moiety. The molecular packing in the crystal phase is nematic-like.
