Quantum Chemical Evaluation of the Electronic Reactivity of Benzimidazole Macromolecules: A Computational Study
A series of benzimidazole derivatives ( E1–E5 ) was synthesized and characterized by FT‐IR and 1 H‐NMR spectroscopy. DFT calculations at the B3LYP/6‐311G(d,p) level were performed to evaluate their electronic properties. Frontier molecular orbital analysis revealed that the HOMO–LUMO energy gap (ΔE) follows th...
