Abstract This work presents a multiscale theoretical investigation into the potential of quinoxaline derivatives (Q1–Q6) as corrosion inhibitors for various metals (Fe(110), Cu(111), and Al(110)). Employing combined approach combining density functional theory (DFT) Monte Carlo simulations, we explore relationship between molecular structure, electronic properties, adsorption behavior. Density dynamics simulations (MDS) were used to investigate characteristics diverse compounds. The study included key parameters including highest occupied orbital energy ( E HOMO ), lowest unoccupied LUMO gap g ) , dipole moment, global hardness, softness σ ionization I electron affinity A electronegativity χ back-donation b−d electrophilicity ω transfer, nucleophilicity ε total (sum zero-point energies). These alongside energies (following trend Q6 > Q2 Q3 Q4 Q5 Q1), are identify promising inhibitor candidates establish structure–property relationships governing their effectiveness. results suggest that efficiency increases with decreasing frontier orbitals. Notably, protonated state exhibits high reactivity, low stability, strong adsorption, making it candidate further exploration. comprehensive offers crucial insights conceptual development new powerful inhibitors.
