New esters of 1,3-dihydroxybenzene and 2,7-dihydroxynaphthalene with 4-(4-alkoxybenzoyloxy)-2-(or 3-)methoxybenzoic acids were synthesized. The correlation between their structure and liquid crystal properties was examined, and the luminescence characteristics of terbium(III) complexes with these esters were studied.

A new series of mesogenic Schiff's base esters, 4-(4′-n-Alkoxybenzoyloxy) 3-methoxy benzylidene 2″-aminonaphthalenes has been synthesized. The synthesized compounds were characterised by elemental analysis and standard spectroscopic methods. All the homologues synthesized exhibit mesomorphism. The mesomorphic properties of the present series are compared with other structurally related series. Chiral nematic mesophase (N*) is induced in the system by doping a derivative of naturally occurring chiral compound.

Three homologous series, having a lateral substituent and different end groups have been synthesized. Series (A) is non-mesogenic while series (B) and (C) exhibit only nematic mesophase. The thermal stabilities of series (B) and (C) are much more lowered compared with the corresponding unsubstituted homologous series. Generally the introduction of a lateral substituent renders the system low melting, and the mesomorphic-isotropic transition temperatures are also lowered. However, in the present study, introduction of a bulky methoxy group as a lateral substituent lowers the mesomorphic-isotropic transition temperatures to a great extent but the melting points are not much depressed.
