Antioxidants Based on Covalently and Ionically Bound Trolox Conjugates

Three types of trolox dimers (bis-trolox derivatives), two of which were pairs of trolox molecules bound symmetrically through an ethylenediamine linker with covalent or ionic bonds and one of which was an asymmetric ionic–covalent conjugate, were synthesized. The water-solubility and antioxidant activity were measured for the synthesized compounds.
