Towards an Efficient Microsystem for the Real‐Time Detection and Quantification of Mercury in Water Based on a Specifically Designed Fluorogenic Binary Task‐Specific Ionic Liquid

Copper(II)‐Specific Fluorogenic Task‐Specific Ionic Liquids as Selective Fluorescence Probes and Recyclable Extractants

“…The major componento fs olid wastes of metallurgical zinc industries is coppera nd it is often considereda so ne of the major hazardoush eavy metal ions in the U.S. [10] Though TSILs are known for extraction of copperf rom aqueous medium,t hey are not very selectivea st wo or more metal ions are extracted simultaneously. [2] Thus controlling the ecological hazards originating from the heavy metal ions is one of the challenges that needs to be addressed by the scientific community.T herefore,e ffective detection of trace amounts of copper and its extraction/removal is an important task.…”

“…However,b oth these methods also rely on ac omplexinga gent as both simple ionic liquids and solid-phase matrixes do not show selectivity as such. [10] Though TSILs are known for extraction of copperf rom aqueous medium,t hey are not very selectivea st wo or more metal ions are extracted simultaneously. [3a, 6] To overcome the selectivity issues and hydration energy of the metal ion for extraction,t ask-specific ionic liquids(TSILs) were developed based on specific functionality tailored for specific functions with additional benefits.…”

Recent progress of task‐specific ionic liquids in chiral resolution and extraction of biological samples and metal ions

“…It was noted that the chiral tropine IL with longer alkyl chain could provide better enantioselectivity. For improving the capability of chiral resolution with ATPS, the same research group developed solid-liquid two-phase [118] systems with dication CILs [62]. L-CIL could cooperatively interact with the L enantiomer of amino acid and copper ion generating a solid phase.…”

Carbazole–azine based fluorescence ‘off–on’ sensor for selective detection of Cu2+ and its live cell imaging

“…In recent years, there have been several attempts to design chemosensors for paramagnetic metal ions. Recently, rhodamine B‐based fluorescent probes have been reported as ‘turn‐on’ fluorescence, and colorimetric, sensors for Cu 2+ . In these sensors, the mechanism involves opening of the spirolactam ring upon binding with a Cu 2+ ion, resulting in fluorescence enhancement.…”
