Abstract

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 Hg2+ ions, as a result of the synergetic binding between CB8, SQ2 and metal cation.
