A novel chemosensor 1 based on a naphthol-bisthiazolopyridine hybrid was synthesized and characterized. Among the various screened cations and anions, chemosensor 1 selectively recognized Ag+ and CN- ions by relying on the color change and distinct absorption and emission changes. Moreover, the probe 1·Ag+ was well operable for the selective monitoring of S2-, HS- and H2S as evidenced by the different color and optical changes. The selective detection of all the anions was simply based on the breakage of the intramolecular hydrogen bonding of 1, followed by the protonation or deprotonation mechanism. In general, chemosensor 1 is a promising indicator in terms of its ease-of-use, selectivity, sensitivity, and rapid response (<1 s). Moreover, the visual detection and concentration determination of these analytes by solution or solid kits are the advantages for the practical applications of this sensor.
基于萘酚-双噻唑并吡啶杂合的新型化学传感器 1 已被合成并进行了表征。在各种筛选出的阳离子和阴离子中，化学传感器 1 通过颜色变化以及明显的吸收和发射变化，选择性地识别 Ag+和 CN-离子。此外，探针 1·Ag+可以很好地用于选择性监测 S2-、HS-和 H2S，这可以从不同的颜色和光学变化中得到证明。所有阴离子的选择性检测都是基于 1 分子内氢键的断裂，随后是质子化或去质子化机制。总的来说，化学传感器 1 在易用性、选择性、灵敏度和快速响应(<1 s)方面具有很大的应用潜力。此外，通过溶液或固体试剂盒对这些分析物进行可视化检测和浓度测定是该传感器实际应用的优势。
