Molecular Docking and DFT Calculations of Anthracene: Insights from Quantum Chemical Methods

Abstract

The molecular structure and spectroscopic data of (2E)-1-(Anthracen-9-yl)-3-(4-nitrophenyl)prop-2-en-1-one are obtained from DFT (B3LYP) with 6-31G(d,p) and 6-31G+(d,p) basis set calculations. The geometry of the molecule is fully optimized, vibrational spectra are calculated and fundamental vibrations are assigned on the basis of potential energy distribution (PED) of the vibrational modes. Molecular parameters such as bond length and bond angle are calculated with the same level of theory. The intramolecular charge transfer is calculated by means of natural bond orbital analysis (NBO). Besides, the molecular electrostatic potential (MEP), HOMO - LUMO, Fukui functions, RDG and ELF are performed. The biological effect is made on the basis of prediction of molecular docking results.
