Abstract

A dual sensing probe for quantitation of NO2−and CN−ions.

A 1:2 co-crystal of 2,2′-thiodibenzoic acid and triphenylphosphane oxide: crystal structure, Hirshfeld surface analysis and computational study

“…In medicine, is dianion is found in the salt Na[EtHg(SC 6 H 4 CO 2 )], which displays anti-fungal and anti-septic activities (Bigham & Copes, 2005). Other uses include as anti-corrosion agents (Chien et al, 2012), as reactive agents or modifiers for nanoparticles and electrochemical sensing (Cang et al, 2017;Sikarwar et al, 2014), as catalysts for organic syntheses (Yang et al, 2018;Selig & Miller, 2011) as well as being the precursor for some anti-viral and anti-microbial agents (Saha et al, 2017). The compound readily coordinates a wide variety of metals, in both neutral and anionic form, due to the presence of both hard (oxygen) and soft (sulfur) donor atoms and exhibits different modes of coordination.…”

A colorimetric fluorescent probe for rapid and specific detection of nitrite

“…Excessive intake of NO 2 in the human body could lead to numerous diseases such as infant methaemoglobinaemia, infant congenital malformation, central nervous system deficiencies, and cancers . The maximum permissible NO 2 − content in water is 21.7 μM stipulated by the United States Environmental Protection Agency (US EPA) . Therefore, we urgently need to develop a simple and efficient method to detect NO 2 − quickly and sensitively.…”

Luminescent Metal Nanoclusters for Potential Chemosensor Applications

“…Moreover, it was applied in real water sample investigations. Instead, thiosalicylic acid-capped Cu NCs with a quantum yield of 13.2% were engaged in the pH-dependent fluorescent "on-off" determination of NO 2 − and CN − ions in water samples [141]. In which, at pH 5.0 and 8.0, the probe approximately quantify the NO 2 − and CN − ions with limits of 5 µM and 5 nM, respectively.…”
