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.
将三(2-吡啶甲基)胺(TMPA)封端的大杯[6]芳烃的大环衍生化,使其能够溶解两种稳定的空气的 Cu(I)/Cu(II) 配合物。这两种配合物具有一个空的配位位,被杯芳烃核心屏蔽在水相环境之外。在纯水中记录的光谱和电化学数据表明,在铜阳离子的两种氧化态下,主体-客体性质都得到了保留。
