摘要：

A new unsymmetrical aniline-based squaraine (SQ2) bearing binding unit of Hg2+ ion was designed and synthesised. SQ2 can form 1:2 inclusion complex with beta-cyclodextrin, and the resulting complex, which undergoes absorption and fluorescence bleaching upon binding Hg2+, can serve as a turn-on colorimetric or fluorescent chemosensor in organic solvent-free aqueous solution for thiol-containing amino acids with high selectivity and tunable measuring range.
