Keywords:Radical trapping antioxidant, bond dissociation enthalpies, ionization energy, potential energy surface, DFT
AbstractIn order to maximize the peroxyl radical trapping capacity of diphenynlamines, the substituents such as N, NMe2, and CF3 are suggested to add to their phenolic rings. The reasonable combination of these substituents at right position can reduce the bond strength of the N-H bond, but still keep the derivatives stable in air.
