Abstract

<p>We prepared two series of liquid crystalline nOCHP5 and nCOCHP5 dimers with two pentyl cyclohexyl phenyl moieties linked to each other by an n methylene chain via ether or ester linkages, respectively, and their liquid crystalline phase behaviors are compared with each other. Both series of dimers form cybotactic A nematic liquid crystals with short-range layer structures to display layer reflections up to second order. With increasing n, the second order reflection increases intensity to be stronger than the first order one, demonstrating the transformation from bilayer to single layer structures. nCOCHP5 forms bilayer structure at longer spacer length than nOCHP5, suggesting that bilayer aggregation of dimers is stabilized due to dipole interaction as well as the π–π stacking of neighboring phenyl rings.</p>
