“…We can recall [41–43] that the mesomorphic thermal ranges and the stabilities of the compounds are affected by the polarity, polarizability and intermolecular interactions between the molecules. Comparison between the orthogonal mesomorphic thermal ranges of both of the series, the series of the compounds with flexible chains on both sides, i.e., 13b are found to exhibit a higher mesomorphic thermal range than the other series, i.e., 13a with phenyl end group.…”

SummaryTwo novel series of unsymmetrically substituted 1,2,4-oxadiazole viz., R.Ox.C*Cn compounds are synthesized and characterized. An optically active, (S)-(+)-methyl 3-hydroxy-2-methylpropionate is used to introduce a chiral center in the molecule. A biphenyl moiety prepared by Suzuki coupling reaction is directly attached to the oxadiazole core at C-5 position. Investigations for the phase behavior revealed that the series with a benzyl group on one end of the oxadiazole core exhibits an 1D orthogonal smectic-A phase while the second series with dodecyl flexible end chain shows orthogonal smectic-A and tilted chiral smectic-C (SmC*) phases over a wide range of temperatures. The smectic-C phase exhibits ferroelectric (FE) polarization switching. The mesomorphic thermal stabilities of these compounds are discussed in the domain of the symmetry and the flexibility of the alkyloxy end chain length attached to the chiral center.

This study focuses on developing an advanced electrode for the electro‐organic Kolbe–Schmitt C–H carboxylation of benzene. The electrode uses copper (Cu) nanoparticles supported on graphene oxide modified with MIL‐101 metal–organic framework (MOF). The MIL‐101 MOF enhances CO2 capture, improving the electrode's efficiency in a deep eutectic solvent (DES) system. The study reports high yields (89%–97%) of synthesized benzoic acids 4(a–l), facilitated by urea/ChCl as a cost‐effective electrolyte, by applying an electric current of 20 mA, in 2 h and at ambient temperature. The innovative electrode design facilitates efficient benzoic acid synthesis, while the use of urea/ChCl as an accessible and cost‐effective electrolyte and solvent enhances the electro‐organic reaction rate. The synthesized benzoic acids were characterized through melting point analysis, 1HNMR spectroscopy, and CHN elemental composition. To assess the electrode's properties, extensive characterization techniques such as XPS, TGA, SEM, EDS, FT‐IR, BET surface area analysis, CV, and FT‐IR were used.
