Chromoionophoric calix[4]arenes (8,9) containing dissociable OH and quaternary pyridinium indicator groups have been synthesized. Optical measurements of the target molecules performed in various solvents in the presence of weak base and alkali cations revealed Li+, Na+ and Ca2+ recognition depending on the binding sites. Solvato- and halochromism of betaines 10,11 formed in situ upon complexation
已合成了含离解性羟基和季吡啶鎓指示剂基团的变色杯[4]芳烃(8,9)。在弱碱和弱碱阳离子存在下,在各种溶剂中对目标分子进行的光学测量显示,取决于结合位点,Li +,Na +和Ca 2+被识别。还观察到在络合时原位形成的甜菜碱10,11的溶剂变色和盐变色现象。
