first study on the electronic effects of ortho-substituents in dendritic antioxidants. Six antioxidants were designed to contain a common phenol ring to provide a baseline antioxidant activity, attached to two other phenol rings with H atoms (reference compound), electron donating groups (EDGs), or electron withdrawing groups (EWGs) ortho to the phenolic OH. These antioxidants were synthesized via reductive
