Synthesis, characterization and mesomorphic investigations of ester-substituted aroylhydrazones possessing a lateral hydroxyl group

The synthesis, characterization and investigation of a new liquid crystalline series of ester containing aroylhydrazones with a lateral hydroxyl group, N-[4-(4′-alkoxy)benzoyloxy-2-hydroxy-benzylidene]-N′- [4″-alkoxybenzoyl]hydrazine (Cm,nLH), with the same or different peripheral alkoxy chains, and some of their nickel(II) and copper(II) complexes are described. All the ligands, except those with no terminal chains on either end of the molecule, exhibit an enantiotropic SmC mesophase, as evidenced by polarizing optical microscopy and differential scanning calorimetric studies. It has been found that addition of a lateral hydroxyl group along with ester-substitution to the aroylhydrazone core increases the mesomorphic as well as thermal stability of the ligands. Also, the coordination of Ni2+ and Cu2+ with the aroylhydraozone core inhibits the mesomorphic potential of the ligands. A temperature dependent Raman study of one of the members, C12,12LH (m = n = 12) has been made to identify phase transitions and to understand the molecular rearrangement as a result of changes in intermolecular interactions at the phase transition. DFT calculations have been performed to obtain the stable electronic structure of the ligand (C6,6LH) and its nickel(II) complex.

Synthesis, characterization, and mesomorphic investigations of diester-substituted salicylaldimines and their copper (II) complexes

A novel homologous series of N-[4-[4′-n-alkoxy)benzoyloxy-2-hydroxybenzylidene)-4-carbethoxy anilines, H2n+1CnOC6H4C(O)OC6H3(OH)C(H)NC6H4COOC2H5 (n = 6, 8, 10, 12, 14, 16) and their copper(II) complexes have been synthesized. All these compounds have been characterized by suitable spectroscopic techniques. The mesomorphic properties of these compounds were investigated by differential scanning calorimetry (DSC) and polarizing optical microscopy (POM). The ligands exhibit wide range of enantiotropic smectic A and nematic phases as confirmed by their typical optical texture under polarizing microscope. The square planar copper(II) complexes of the ligands show only an isotropic phase at higher temperature and no mesogenic nature is observed. DFT calculations have been performed using GAUSSIAN-03 program at B3LYP level to obtain the stable electronic structure of the ligand with decyloxy chain length and its copper(II) complex.

Synthesis and characterization of banana-shaped mesogens derived from a benzophenone moiety

A homologous series of Schiff's bases consisting of a benzophenone moiety as the central core has been synthesized. Schiff's bases were prepared starting from benzophenone by a sequence of reactions, viz., nitration followed by reduction and heating the r

Synthesis, mesophase behavior and thermal stability of liquid crystals based on different central linkages with lateral substitution and terminal heterocyclic moieties

The synthesis and evaluation of thermal behavior of two new mesogenic homologous series of liquid crystalline compound containing 1,2,4-triazole and isonicotinic acid ring at the terminus of the molecule have been reported, viz. 3-hydroxy-4-[(4-1,2,4-triazol-4-ylimino)methyl] phenyl 4-alkoxybenzoate (Series-I) and 3-hydroxy-4 (isonicotinoyl carbonohydrazonoyl) phenyl 4-alkoxy benzoate (Series-II). The compounds of both the series have been characterized by elemental Analysis, FT-IR, mass spectrometry, 1H-NMR and 13C-NMR. Phase transition temperatures and the thermal parameters were obtained from differential scanning calarimetry (DSC). The texture observation was performed under polarizing optical microscopy (PMO) attached with Mettler hot stage. All the derivatives are mesomorphic in nature showing nematic phase as well as higher members of both the series show smectic phase. The use of triazole and isonicotinic acid as a terminal group has a very dramatic effect on the melting and clearing points. Similarly lateral-OH substitution on central phenyl ring shows higher clearing temperature due to intermolecular hydrogen bonding. The mesomorphic behavior has been analyzed in terms of structural property relation. Copyright Taylor & Francis Group, LLC.

Synthesis and characterization of unsymmetrical five-ring achrial banana-shaped compounds with a B2 phase

Synthesis, characterization, and mesomorphic properties of new liquid-crystalline compounds involving ester-azomethine central linkages, lateral substitution, and a thiazole ring

In continuation with our work on liquid crystals with unconventional molecular structures, two homologous series that have 1,4-disubstitution and 1,3,4-trisubstitution in the central phenyl ring, such as 2[(4-n-alkoxy- benzyloxy) phenyl azomethine]-5-methyl thiazole and 2-[(4-n-alkoxy-benzyloxy)-2- hydroxy salicyladimine]-5-methyl thiazole, have been synthesized. They have been characterized by elemental analysis, FT-IR, 1HNMR, 13CNMR, and mass spectrometry. The liquid-crystalline behavior of these compounds was observed by differential scanning calorimetry (DSC) and polarizing microscopy. All the compounds of the 1,4-disubstituted series show an enantiotropic nematic phase only, whereas the compounds of the 1,3,4-trisubstituted series show smectic and nematic phases. Some mesogens with a lateral hydroxy group were also synthesized to evaluate the effect of this group on melting point, transition temperatures, and mesophase morphology.
