A new heteroditopic chemosensor based on the 1,3-alternate conformation of thiacalix[4]crown shows a ratiometric fluorescence response towards Hg(2+) ions. Further, a negative allosteric behaviour between Hg(2+)/Li(+) ions is observed. Thus, metal ion exchange triggers a Hg(2+)/Li(+) switchable fluorescent chemosensor.
一种基于硫代杯[4]冠醚 1,3-交替构象的新型杂位化学传感器对 Hg(2+)离子表现出比率荧光响应。此外,还观察到 Hg(2+)/Li(+)离子之间的负变构行为。因此,金属离子交换触发了 Hg(2+)/Li(+)可切换荧光化学传感器。
