杯芳烃的超分子化学研究（Ⅰ）

Studies on Supramolecular Chemistry of Calixarenes ()\= Liquid Membrane Transport of K\++, Na\++ Ions with \=\%p\|tert\%\|Butylcalix\{\ \}arenes and Their Derivatives as Carriers

杯芳烃的液膜传输作用是其典型的超分子化学特征之一［１］．在探索杯芳烃及其衍生物作为流动载体传输金属离子的能力及传输作用的规律性，以及模仿细胞壁两边金属离子的传递过程及其控制方式方面有潜在应用前景．Ｉｚａｔ［２］等认为，只有当源相处于强碱性条件（ｐＨ＞...

The liquid membrane transports of K\++ ions by \%p\|tert\%\|butylcalix\{\ \}arene as carrier are investigated by the bubbling \%pseudo\%\|emulsion liquid membrane. This transport process is a proton\|coupled transport with a coupled flow of protons in opposite direction. The driving force for the transport is the pH gradient between the source phase and the receiving phase. The selected transport for K\++ ion or Na\++ ion by \%p\|tert\%\|butylcalix\{\n\]\}arene(n=4, 6, 8) as carriers are investigated.
