A multisensing ratiometric fluorescent sensor for recognition of Al3+, Th4+ and picric acid

Hydrogen bond directed high-fidelity optical detection of picric acid: A single driver on diverse roads towards the same destiny

“…6) colorimetrically recognized Al 3+ , Th 4+ , and PA independently in MeCN. 80 With the gradual addition of PA in a solution of 33 , a red shift in the emission maximum (from 418 to 483 nm) was noted along with a distinct naked-eye color change from blue to yellow. The probe was effective in detecting PA over a wide pH range (4 to 7) with exceptional sub-nanomolar sensitivity (LOD = 0.53 nM).…”

Smart crystalline framework materials with a triazole carboxylic acid ligand: fluorescence sensing and catalytic reduction of PNP

“…Therefore, precise recognition and detection of Th 4+ and UO 2 2+ are crucial. 44,45 At present, the detection methods for water pollutants are rapidly advancing. Commonly used techniques include electrochemical detection, ion mobility spectrometry, photoelectric chemical detection and plasma hydrogel.…”

Chemically modified graphitic carbon nitride nanosheets for the selective turn-off fluorescence detection of Al(iii) ions in crabs (Brachyura)

“…deodorants) as well as in water treatment. 3–5 The excessive industrial utilization of Al( iii ) resulted in critical environmental acidification that lead to serious effects on the environment quality and human health. 6 Therefore, the World Health Organization (WHO) recommends 7.4 mM as the maximum permissible amount of Al( iii ) in drinking water.…”
