A REDOX-SWITCHABLE MOLECULAR RECEPTOR-BASED ON ANTHRAQUINONE

The reaction of two equivalents each of bisphenol A with 1,5-dichloroa nthraquinone in the presence of base leads to a molecular box designed to be electroactive. The compound is fully characterized, it exhibits reversible redox behavior, and its solid state structure has been obt ained. Two molecules of toluene are present in the crystal lattice but these are not located within the receptor's cavity. Evidence for an i nteraction of ferrocene (guest) with a precursor to the molecular box is described.
