designed and synthesized for selective ion sensing. Each probe acted as strong colorimetric sensors for fluoride and cyanide ions and exhibited intramolecular charge transfer (ICT) band, which showed significant red-shifts after addition of either the F– or CN– ion. One of the probes (2) showed selective colorimetric sensing for both cyanide and fluoride ions. In organic medium, 2 showed selective
设计并合成了基于蒽[1,2 - d ]咪唑-6,11-二酮的探针,用于选择性离子感测。每个探针充当氟化物和氰化物离子并显示出分子内电荷转移(ICT)带强比色传感器,这表明添加的任一在F后显著红移-或CN -离子。探针之一(2)对氰化物和氟离子均显示选择性比色传感。在有机介质中,2显示出氟化物和氰化物的选择性颜色变化,而在水性有机介质中,它对氰化物离子显示出选择性的比例响应。
