Abstract
Potassium ferricyanide in an aqueous solution is easily decomposed into highly toxic substances (potassium cyanide and hydrogen cyanide) by light or alkaline action, which poses a major hazard to environmental and human health. Here, a reticulated aggregation-induced emission (AIE) supramolecular polymer material (TPAP-Mb@tQ[14]) was prepared by the supramolecular self-assembly of twisted cucurbit[14]uril (tQ[14]) and a triphenylamine derivative (TPAP-Mb). TPAP-Mb@tQ[14] not only recognizes Fe(CN)63- with sensitive specificity with a limit of detection (LOD) of 1.64 × 10-7 M but can also effectively remove and adsorb Fe(CN)63- from an aqueous solution with a removal rate as high as 97.38%. Meanwhile, an important component of the supramolecular polymer material (tQ[14]) can be reused. Thus, the tQ[14]-based supramolecular assembly has the potential to be used for applications addressing toxic anionic contaminants present in aqueous environments.
