Structure-property correlations of the following model compounds for oligomer liquid crystals (LCs) have been investigated: monomers, C6H5O (CH2) x CH3 (x= 4 and 5); dimers, C6H5O (CH2) x OC6H5 (x= 3, 4, 5, and 6); and tetramers, C6H5O (CH2) x OC6H4O (CH2) x OC6H4O (CH2) x OC6H5 (x= 5 and 6). Deuterium NMR quadrupolar splittings observed from the deuterated model compounds dissolved in a nematic solvent, 4'- ...
