A new tripodal receptor and a novel dyed mesoporous material are presented. The presence of thioureas conjugated with azobenzene chromophores enables the selective colorimetric detection of mercury(II) cations in THF through a remarkable colour change from yellow to deep purple.
本文提出了一种新的三足受体和一种新型染料介孔材料。由于含有与偶氮苯生色团相连的硫脲基团，该材料在四氢呋喃中对汞(II)阳离子表现出选择性的比色识别，颜色由黄色变为深紫色，变化非常明显。
