L. Echegoyen et al., PREPARATION AND ELECTROCHEMICAL SWITCHING OF NOVEL BIS(ANTHRAQUINONE)DIAZACROWN ETHERS, Tetrahedron letters, 35(34), 1994, pp. 6383-6386
Novel bis (anthraquinone)diazacrown ethers 1 and 2 were prepared by nu
cleophilic displacement reactions on 1-fluoro-9,10-anthraquinone by di
azacrown ethers. The electrochemically switched enhanced sodium bindin
g capabilities of these compounds with Na+ were evaluated. Both compou
nds exhibited enhanced sodium binding properties upon electrochemical
reduction.
