In this study, we describe the synthesis and structural characterization of novel 3,6,8-trimethoxyquinoline (2) by X-ray, FT-IR, NMR analysis, and its computational investigations. The molecular geometry of title coumpound was also optimized by using density functional theory (DFT/B3LYP) and Hartree-Fock (HF) methods with the 6-311 G(d,p) basis set, and geometric parameters were compared with the experimental data. Theoretical calculations are a good way for obtaining comprehensive information about global and local chemical activity, and chemical and molecular properties that reveal the nucleophilic and electrophilic nature. Molecular electrostatic potential (MEP) distribution, thermodynamic parameters, frontier molecular orbitals (FMOs), Fukui functions, and net charge analysis of (2) were also investigated. Also, the interactions between the molecule with DNA bases such as guanine, adenine, thymine, and cytosine were investigated by using the electrophilicity-based charge transfer (ECT) method and charge transfer (Delta N) for investigating the charge transfer, electrophilic, and nucleophilic nature.
