چکیده انگلیسی
A quinolinocyclodextrin, that is, MQAS-β-cyclodextrin (MQAS = N-(2-methyl-8-amino- quinolyl)-p-aminobenzene sulfonamide) was synthesized. Further experiments showed that it could form very stable stoichiometric 2:1 complex with Zn2+ in water. Significantly, the resultant quinolinocyclodextrin/Zn2+ complex showed the specific fluorescence response to Hg2+ over other metal ions, which could be readily distinguished in either aqueous solution or the PVA-based thin film. This finding would enable Zn·32 complex as a convenient and highly efficient fluorescence sensor for the detection of Hg2+.
