Special Issue Information

Dear Colleagues,

New materials with desired properties are the material basis for the development of high-end manufacturing and the forerunner of high-tech development. The application of key technologies in material design transforms from traditionally trial-and-error R&D model into a new model that involves parallel association in the whole process, completely accelerating the entire process of material discovery, development, production and eventually promotes the engineering application.

Of particular significance is the possibility of using machine learning assisted high-throughput calculations and multi-scale simulations, along with electron tunneling and neutron scattering techniques to investigate and discover new materials with desired structural and electronic properties for technological innovation.

In this Special Issue, modern trends of advanced theoretical approach and experimental technique, including density functional theory calculation, molecular dynamics simulation, monte carlo simulation, multi-scale modeling, high-throughput calculation, machine learning, neutron scattering, synchrotron x-ray scattering, scanning tunneling microscope, transmission electron microscopy, etc., are highlighted and discussed.

It is my pleasure to invite you to submit a manuscript for this Special Issue. Full papers, communications, and reviews are all welcome.

Abstract
New three-ring ester/azomethine homologues series, (E)-4-((4-hydroxybenzylidene)amino)phenyl 4-(alkoxy)benzoate In, were prepared and their properties were investigated experimentally and theoretically. FT-IR, NMR, and elemental analyses were used to confirm the chemical structures of the synthesized compounds. The mesomorphic activities of the planned homologues [...] Read more.
New three-ring ester/azomethine homologues series, (E)-4-((4-hydroxybenzylidene)amino)phenyl 4-(alkoxy)benzoate In, were prepared and their properties were investigated experimentally and theoretically. FT-IR, NMR, and elemental analyses were used to confirm the chemical structures of the synthesized compounds. The mesomorphic activities of the planned homologues were evaluated using differential scanning calorimetry (DSC) and polarized optical microscopy. All of the homologous examined were found to have non-mesomorphic properties. Theoretical calculations using the density functional theory (DFT) were used to validate the experimental data and determine the most stable conformation of the synthesized compounds. All calculated conformers’ thermal properties, dipole moments, and polarizability were discussed. The results show that the terminal alkoxy chain length affects the thermal parameters of the conformers. The correlations between these parameters’ values and the conformer type were demonstrated. The base component was expected to be in two conformers according to the orientation of the N atom of imine-linkage. DFT calculations revealed the more probable of the two possible conformers, and the incorporation of the alkoxy terminal chain in one position affect its geometrical and mesomerphic characteristics.
