The present research article deals with the comparative thermodynamical and electrical studies of the compounds 4-n-decyloxy-4'-(cholesteryloxycarbonyl-1-butyloxy) chalcone (DC-4, 10), 4-n-undecyloxy-4'-(cholesteryloxycarbonyl-1-butyloxy) chalcone (DC-4, 11) and 4-n-dodecyloxy-4'-(cholesteryloxycarbonyl-1-butyloxy) chalcone (DC-4, 12) in order to generalize the electrical (mainly dielectric anisotropy, experimental slopes of inverse of dielectric strength with temperature and rotational viscosity) behaviors of the Twisted Grain Boundary (TGB) phases. The research article also explores the effect of the increase in the length of the alkyl chains on the dielectric properties of the above studied compounds.
