Application

  • Cation-Selective and Anion-Controlled Fluorogenic Behaviors of a Benzothiazole-Attached Macrocycle That Correlate with Structural Coordination Modes.: This study explores the fluorogenic behaviors of a benzothiazole-attached macrocycle, which exhibits cation-selective and anion-controlled properties. The research highlights the structural coordination modes that influence these behaviors, providing insights into the development of chemical sensors and analytical methods utilizing Mercury(II) iodide as a key component. (Ju et al., 2016).
