Abstract

The liquid crystallinity values of 2-fluorenyl 4-alkyl (pentadecyl, n-, or s-butyl)-benzoates were compared with those of biphenyl homologues. Cyano group or hydrogen was used as the end group at the 7-position of 2-fluorenol moiety. Methoxy and hydroxy groups in addition to hydrogen were examined as a lateral substituent at the 2-position of 4- alkylbenzoic acid unit. 7-Cyano-2-fluorenyl 2-hydroxy-4-pentadecylbenzoate shows very ...
