Resumen:
A molecular recognition process has been used to form newmesogenicmolecular structures, where intermolecular hydrogen bonding occursbetween 4-(octyloxy)benzoic acid (8BAO) and four 4-alkylbenzoic acids(nBAs, n = 2, 5, 6, 7). The synthesis of these complexes has beenattained by resorting to mechanochemistry. The resulting materialshave been characterized by polarizing optical thermal microscopy, differentialscanning calorimetry, vibrational spectroscopy, X-ray powderdiffraction, and 1H NMR relaxometry. All the elements of the series showthe formation of a mesophase. For one of the complexes, its electroopticalproperties have also been assessed, resulting comparable tothose of other widely used liquid crystals.
