Translational order parameter in the smectic-B phase of 4-hexyl-4′-[2-(4-isothiocyanatophenyl)ethyl]-1,1′-biphenyl

Smectic translational order parameter in two liquid crystalline compounds

“…[12] Accordingly, the X-ray intensity I(T) at a temperature T computed by calculating the area under the corresponding small angle (001) smectic X-ray intensity peak can be expressed as…”

“…In our earlier paper, we had reported TOP in the SmB phase of the compound 4-Hexyl-4 0 -[2-(4-isothiocyanatophenyl) ethyl]-1,1 0 -biphenyl. [12] As an extension of this work, in this manuscript, we are reporting the TOP in the smectic phase(s) of (1) p-cyanobenzylidene p-nonyloxyaniline (CN.9) and (2) pdecyloxybenzylidene p-butylaniline (10O.4) by X-ray method. The molecular structures of these compounds are shown in Figure 1.…”
