1,8-azabis(ethyleneoxyethyleneoxy)-[N-amine]anthracene-9,10-dione, where amine = N-(aminomethyl)-1-benzyl (2), N-(aminomethyl)-1-napthyl (3), N-(aminomethyl)-9-anthracenyl (4) and N-(aminomethyl)-1-pyrenyl (5) were obtained by reacting 1,8-bis(2-bromoethyleneoxyethyleneoxy)anthracene-9,10-dione (1) with the benzylamine, napthyl amine, 9-methylaminoanthracene, 1-pyrenylmethanamine hydrochloride, respectively, in the presence of NaI, Na2CO3 at 85 °C in acetonitrile for 6 hours. All new macrocycles were characterized by spectroscopic methods and elemental analyses. Additionally compound 4 was characterized by single-crystal X-ray crystallography to confirm its structure.

520 $a 1,8-azabis(ethyleneoxyethyleneoxy)-[N-amine]anthracene-9,10-dione, where amine = N-(aminomethyl)-1-benzyl (2), N-(aminomethyl)-1-napthyl (3), N-(aminomethyl)-9-anthracenyl (4) and N-(aminomethyl)-1-pyrenyl (5) were obtained by reacting 1,8-bis(2-bromoethyleneoxyethyleneoxy)anthracene-9,10-dione (1) with the benzylamine, napthyl amine, 9-methylaminoanthracene, 1-pyrenylmethanamine hydrochloride, respectively, in the presence of NaI, Na2CO3 at 85 °C in acetonitrile for 6 hours. All new macrocycles were characterized by spectroscopic methods and elemental analyses. Additionally compound 4 was characterized by single-crystal X-ray crystallography to confirm its structure.
520 $a The compounds 1-5 show characteristic, first and second, one-electron, reversible, anthraquinone reduction potentials. Apart from the anthraquinone's reversible reduction potentials, 2-5 gave an irreversible oxidation peak for amine and reversible peak for polyaromatics in the cyclic voltammogram. Luminescence changes for compounds 1-3 were studied by mixing macrocycles with a battery of different metal ions in a 1:2 ratio in acetonitrile to determine the selectivity towards metal ions. Although structurally they are similar, we found that these compounds show different selectivity behavior. Compound 2 is highly luminescent and doesn't show any selectivity. Compound 3 shows best selectivity for Hg(II) and Cu(II), compound 4 shows selectivity for Mg(II), and 5 shows selectivity for Hg(II).
