Synthesis and Studies of a Water-Soluble and Air-Stable Cu-I/Cu-II Open-Shell Funnel Complex

Abstract : The derivatization of the large rim of a TMPA-capped calix[6]arene (TMPA = tris(2-pyridylmethyl)amine) with three trimethylammonium groups enables the water-solubilization of two air-stable Cu(I)/Cu(II) complexes. These two complexes present a vacant coordination site shielded from the aqueous environment by the calixarene core. The spectroscopic and electrochemical data recorded in pure water indicate that the host guest properties of the funnel complex are retained in both oxidation states of the copper cation.
