N2 - Infinite-dilution activity coefficients (γ2∞) and partial molar excess enthalpies and entropies obtained using gas-liquid chromatography are reported for 10 solutes, varying in molecular size, shape and flexibility, in the isotropic and the nematic phases of the ethyl, propyl, butyl, pentyl, hexyl, and heptyl members of the p-cyanophenyl p-n-alkybenzoate homologous series of liquid crystals. General trends in the six solvents are identified. The results, which corroborate earlier results, demonstrate the effects that the solute structure and the length of the flexible alkyl tail on the solvent molecule have on the solution process.
