ABSTRACT The tetrazole-functionalised calixdiquinone 5,17-di-tert-butyl-26,28-bis-(1H-tetrazole-5-ylmethoxy)-calix[4]-25,27-diquinone Q was synthesised by chemical oxidation of the bis-tetrazole calix[4]arene precursor using PbO2/HClO4. The single crystal X-ray structure determination of Q confirmed the structure and showed binding of a water molecule in the solid state. Chemical reduction of Q to the dihydroquinone QR was achieved using N,N-diethylhydroxylamine. Comparison of the solution phase photophysical properties of Q or QR in the presence of terbium ions showed significant excitation only with QR, suggesting redox switching of the photophysical response may be possible with this or similar receptor.

镧系元素与四唑取代的杯[4]二醌和杯[4]二氢醌配位

摘要 四唑官能化的杯二醌 5,17-二叔丁基-26,28-双-(1H-四唑-5-基甲氧基)-杯[4]-25,27-二醌 Q 是通过化学氧化合成的使用 PbO2/HClO4 制备双四唑杯 [4] 芳烃前体。Q 的单晶 X 射线结构测定证实了结构，并显示出固态水分子的结合。使用 N,N-二乙基羟胺将 Q 化学还原为二氢醌 QR。在铽离子存在下，Q 或 QR 的溶液相光物理特性的比较显示仅用 QR 显着激发，这表明光物理响应的氧化还原转换可能使用这种或类似的受体。图形概要
