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 similar properties to those of 4'-cyanobiphenyl-4-yl 2-hydroxy-4-pentadecylbenzoate
