“…In one demonstration of this approach, the acridinone-appended silyated alkyne 2 was allowed to react with CH 3 HgX (X ) Cl, Br) in dichloromethane and in the presence of TBAF, and the resulting methylmercury acetylide 3 was detected by HPLC/UV (Figure 2a). 62 When excess 2 is employed,>85% formation of 3 occurs in 20 min at 20 °C. The sensitivity of this method is high; concentrations as low as 6 nM methylmercury were detected.…”

“…It is well known that Hg exists in natural waters as different species: Hg 0 , methyl-Hg, and inorganic Hg(II); however, the dominant toxic species in drinking waters is Hg(II). Various instrumental methods and techniques have been developed for Hg determination at low environmentally relevant concentrations like atomic absorption/emission spectrometry (AAS/AES) [3], atomic fluorescence spectrometry (AFS) [4,5], and high-performance liquid chromatography (HPLC) [6,7]. In spite of being very sensitive and precise for Hg determination, these methods often require a time-consuming sample preparation step as well as expensive instrumentation.…”

“…An important challenge in this regard is to detect these ions and molecules in biological systems and to quantify so as to provide diagnosis for the disease. Therefore, the development of small molecular probes for sensitive and selective detection of ions and molecules is an important task and stands as a contemporary topic of research in the current literature [28–32] …”
