In this study, the synthesis, characterization, and mesomorphic properties of ten new bent-rod compounds containing two units of 1,2,4-oxadiazoles are reported. In order to understand the relationship between the structure and the mesomorphic behavior, molecules containing a variety of polar substituents (i.e., I, NO2, NH2, OH) on the central rigid core were prepared. The hexagonal columnar mesomorphism was characterized by DSC and POM and the nature of the mesophases was established through XRD studies. The driving force for self-assembly can be explained by microsegregation between the aliphatic parts and the polar parts, producing a dimer, trimer, and tetramer inside a single disc.

The use of 1,2,4-oxadiazol-5-ones, a recently developed class of bioisosteric replacements for carboxylic acids in medicinal chemistry, as binding ligands in supramolecular complexes is reported and has been exemplified by the formation of non-covalent co

Micelles of cetyltrimethylammonium chloride (CTACl) only weakly speed the benzamidoximate-mediated dephosphorylation of p-nitrophenyl diphenyl phosphate (pNPDPP) at pH 10.7 because the amidoximate binds only weakly to CTACl and is only slightly deprotonat
