SQ2 squaraine染料与葫芦[8]uril （CB8）之间的结合相互作用通过形成1:1包合物有效地去除水溶液中SQ2的聚集。得到的SQ2。CB8配合物表现出Hg（2+）离子的高选择性荧光猝灭，这是CB8、SQ2和金属阳离子协同结合的结果。
The binding interactions between SQ2 squaraine dye and cucurbit[8]uril (CB8) effectively removes the aggregation of SQ2 in aqueous solution by forming a 1 : 1 inclusion complex. The resulting SQ2.CB8 complex exhibits highly selective fluorescence quenching by Hg(2+) ions, as a result of the synergetic binding between CB8, SQ2 and metal cation.
