1-[([1,1(I)-Biphenyl]-4-yl](phenyl)methyl]-1H-imidazolium-2,5-dichloro-3,6-dihydroxy-cyclohexa-2,5-diene-1,4-dione (BCAA) and 1-[([1,1(I)-Biphenyl]-4-yl](phenyl)methyl]-1H-imidazolium-4,5-dichloro-3,6-dioxocyclohexa-1,4-diene-1,2-dicarbonitrile (BDDQ) were synthesized and characterized using spectral analysis. The fundamental structural aspects of these derivatives have been examined based on optimized geometry, spectroscopic behavior, intermolecular interaction, chemical reactivity, and molecular docking analysis. The most stable minimum energy conformer of the title molecules was identified by potential energy surface scan along the rotational bonds. Accordingly, global and local chemical reactivity descriptors were investigated. The wavenumber downshift of different modes is noted. Title molecules exhibit inhibitory activity against different receptors.
