基于亚胺蒽醌衍生的冠醚,合成得到了一对新的生色离子载体1和2,其中化合物1显示出对Ba2+和Ca2+的选择性生色传感,而化合物2则对Mg2+显示出高选择性与高灵敏性的"肉眼"识别性能.
A couple of new chromoionphores 1 and 2 based on iminoanthraquinone derived crown ether were synthesized.Compound 1 showed remarkable color changes in the presence of Ba2+ and Ca2+,while compound 2 showed high sensitive and selective 'naked-eye' recognition toward Mg2+ over other tested ions.
