Molecular structure, vibrational spectroscopy (FT-IR, Raman), solvent effects, molecular docking and DFT studies of 1-(4-chlorophenyl)-3-(4-ethoxyphenyl)-prop-2-en-1-one

In this present work, a chalcone derivative 1-(4-Chlorophenyl)-3-(4-ethoxyphenyl)-prop-2-en-1-one is in-vestigated using the density functional theory. PES scan is used to find the most stable conformational structure of the title compound. The geometrical parameters, FT-IR and FT-Raman spectra are performed by the DFT method with B3LYP/6-311 + G basis set, which are very comparable with the experimental results. UV-Vis spectrum, frontier molecular orbitals, global reactivity descriptors, molecular electrostatic potential surface, NLO parameters and Mulliken charge in the gas phase, various polar and non-polar solvents are performed to reveal solvents effect. Further, it is found that the electronic properties show a good correlation with the polarity of solvents. Hirshfeld Surface analysis demonstrates H middotmiddotmiddotH contact is dominant in the crystal packing. By means of molecular reactivity descriptors such as natural bond orbital analysis, Fukui function and dual descriptor analysis, the chemical reactivity is theoretically esti-mated. ELF and LOL are used to access the energy density of electrons. Molecular docking illustrates ECC may be a potential inhibitor for 6R3K protein.(c) 2022 Elsevier B.V. All rights reserved.
