A new rhodamine-benzothiazole conjugated colorimetric sensor 1 that exhibits sequential recognition to Cu(2+) and S(2-) in CH3CN/HEPES buffer (v/v=1:1, HEPES 10mM, pH=7.0) solution has been developed. Sensor 1 displays highly selective and sensitive recognition to Cu(2+) with a ratiometric behavior, and the resultant 1-Cu(2+) complex can act as a highly selective S(2-) sensor via Cu(2+) displacement approach. The Cu(2+) and S(2-) recognition processes are rapid and reversible, and the Cu(2+) and S(2-) inputs can result in an INHIBIT logic gate.
已开发出一种新型罗丹明 - 苯并噻唑共轭比色传感器1，该传感器在乙腈/HEPES缓冲液（v/v = 1:1，HEPES 10mM，pH = 7.0）溶液中对Cu(2+)和S(2-)具有顺序识别能力。传感器1对Cu(2+)表现出高度选择性和灵敏的比率识别行为，并且所得的1 - Cu(2+)络合物可通过Cu(2+)置换方法作为高度选择性的S(2-)传感器。Cu(2+)和S(2-)的识别过程快速且可逆，并且Cu(2+)和S(2-)输入可产生一个抑制逻辑门。
