“…Liquid crystal dimers are usually prepared by covalently linking two mesogens to a flexible spacer (1)(2)(3)(4). In recent years, it has been recognized that molecular recognition processes between different molecules through non-covalent interactions are advantageous for the design of functional molecular aggregates as liquid crystals and crystalline materials (5)(6)(7).…”

Two new series of hydrogen bonding liquid crystal dimers were prepared and their selfassemble behavior and structure-property relationships were studied through intermolecular hydrogen bond formation. The first series of symmetric liquid crystal dimers have two terminal alkoxy chains and the second have four terminal alkoxy chains. Their structures were elucidated using spectroscopic techniques, elemental analysis, and powdered X-ray diffraction. The mesophases and their corresponding transition temperatures were identified by differential scanning calorimetric measurements and polarized optical microscope.
