Abstract: A systematic crystallization kinetic study using thermal microscopy and diOE erential scanning calorimetry has been carried out on two novel liquid crystalline compounds, DBA : MHB and DBA : ACP. These involve intermolecular hydrogen bonding between 4-n -decyloxybenzoic acid (DBA) and methyl 4-hydroxybenzoate (MHB); and between DBA and 2-amino-5-chloropyridine (ACP). The kinetics experiments were performed from the crystal G phase, which is a common induced kinetophase in both the compounds. Further, the proto… Show more

“…The formation of these hydrogen bonds played crucial role in self assembling process and building organized molecular structures [5,6]. In previous studies many liquid crystalline materials were synthesized with either mesomorphic or non-mesomorphic [7][8][9][10] compounds cross linked by non-covalent interactions [11,12] and with inducement of phases [13][14][15][16][17] attracted more interest that hold promise in potential applications [9] leading to supramolecular structures [18] due to its stability and directionality [19]. With untiring efforts and quest in the development, new liquid crystals are attributed between the p-n-alkoxy benzoic acids and cinnamamide.…”

“…Although the first reports of H-bonding in LCs date back to the 1960s [3,4], much research took place in the last two decades of the twentieth century [5][6][7][8][9][10][11][12][13][18][19][20][21][22]. It was noticed that their lower bonding and activation energies showed a profound influence on their thermal properties, viz.…”

“…In continuation of our systematic investigation of Hbonded liquid crystals comprising different proton and acceptor groups [19][20][21][22][23], the present communication deals with the synthesis and phase behaviour of a new series of liquid crystalline systems involving intermolecular hydrogen bonding between p-n-alkoxybenzoic acids (nABA) and p-aminobenzonitrile (ABN). The molecular structure of the ABN:nABA series is represented in Figure 1.…”

“…In fact, it has been widely accepted that the proton donor and acceptor capabilities of the atoms of the functional groups involved in the hydrogen bonding contribute remarkably to the occurrence of new phases and their thermal stability. Despite their low bond activation energies, these non-covalent interactions show a profound impact on thermal and physical properties such as melting points, heats of vaporization, mesomorphic behaviour, etc.In continuation of our systematic investigation of Hbonded liquid crystals comprising different proton and acceptor groups [19][20][21][22][23], the present communication deals with the synthesis and phase behaviour of a new series of liquid crystalline systems involving intermolecular hydrogen bonding between p-n-alkoxybenzoic acids (nABA) and p-aminobenzonitrile (ABN).
