第一个用于硫阴离子的近红外荧光传感器是基于位移方法构建的。该传感整体由花青染料、哌嗪连接体、8-氨基喹啉配体和铜组成。该传感器的优点包括在乙醇水溶液中具有大的近红外荧光开启信号、高灵敏度和高选择性。基于过渡金属的置换策略可能为开发用于各种阴离子目标的近红外荧光传感器开辟一条途径。
The first NIR fluorescent sensor for sulfide anions was constructed based on the displacement approach. The sensing ensemble is composed of a cyanine dye, a piperazine linker, an 8-aminoquinoline ligand, and copper. The favorable attributes of the sensor include a large NIR fluorescence turn-on signal in aqueous ethanol, high sensitivity, and high selectivity. The transition-metal-based displacement strategy may open an avenue for development of NIR fluorescent sensors for a wide variety of anion targets.
