“…Within the large class of calamitic liquid crystalline compounds, typically formed by a conformationally rigid and linear mesogenic core to which flexible alkyl tails are attached, bent mesogenic cores are comparatively few. Examples are given by several mesogens containing five-membered aromatic heterocyclic rings, such as oxadiazoles, isoxazoles, pyrazoles, triazoles, benzoxazoles and carbazoles (Girdziunaite et al, 1991;Caruso et al, 1992;Centore et al, 1996;Benbayer et al, 2013;Lu et al, 2014;Li et al, 2015b;Tomi et al, 2016;Saha et al, 2017;Hu et al, 2017Hu et al, , 2018.…”

Supporting information: this article has supporting information at journals.iucr.org/c Crystal structure and mesogenic behaviour of a new fluorene derivative: 9,9-dimethyl-2,7-bis(4-pentylphenyl)-9H-fluoreneThe title compound, C 37 H 42 , 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 bisphenyl fluorene moiety. The molecular packing in the crystal phase is nematiclike.

“…In the field of mesogenic materials, some liquid crystals containing the 1,2,3-triazole ring have been synthesized, and exhibit multiform liquid-crystalline mesophases with a lower melting temperature and a wide thermal range useful in device applications [14][15][16][17][18][19][20]. Recently, we have reported a series of 1,2,3-(NH)-triazolyl ferrocenomesogens with good redox activity [21].…”
