AbstractR-(+)- and S-(-)-2-octyl-[4"-decyloxy-3,3'-difluoro]-4-terphenylate (4-DDOT) were synthesized and characterized completely for possible use in laser-addressed displays. The pertinent structural features in this compound are the 3,3' positions of the lateral Fluorines in the ring and the respective donor- acceptor effect of the alkoxy terminal functionalities to extend aromatic conjugation . A not so large Fluorine separation favors the formation of a Smectic A phase, the phase, which is desirable for the aforementioned type of displays .Spectroscopic techniques such as 1H NMR, 13C NMR, and FTIR were employed for structural determination. DSC (for determination of transition temperatures), OPM and X-ray (for mesophase identification) measurements were also done. These compounds were also subjected for polarimetric measurements. Cambridge and ACD lab Software molecular modeling program were employed for structural determination and theoretical comparison.
