Abstract Share this page

Gas chromatography was used to study of the retention of xylene, methylanisole, and lutidine on stationary phases based on nematic 4-ehtyloxy-4′-(6-hydroxyhexyloxy)azobenzene, 4-ethyloxy-4′(3-hydroxypropyloxy)azobenzene, and 4-ethyloxy-4′-(6-hydroxyhexyloxy)azobenzene. A thermodynamic explanation of the structural selectivity of the liquid-crystalline phases of the considered compounds is proposed.
