Iridium (III) complex-based fluorescent probe for detection of thiophenols and its application in water samples

Recent Progress in the Development of Fluorescent Probes for Thiophenol

“…The photoluminescence response was also very sensitive ( k = 91.92 × 10 6 M −1 ) with a determined LOD of 2.5 nM. Recently, Zhang and Pu et al reported another cyclometalated iridium(III) complex ( 12 ) (Figure 5) for detecting PhSH [72].…”

Naked‐eye detection of Cu (II) and Fe (III) based on a Schiff Base Ruthenium complex with nicotinohydrazide

“…In recent decades, optical sensors, especially fluorescent probes have become an important approach to detect various chemical substances due to their evident advantages in simple operation, fast response, high selectivity and sensitivity, and biological imaging. [ 25–29 ] Usually, the d 6 , d 8 , d 10 ‐electron structure transition metal complexes usually exhibit significant Stokes shifts, long‐lived phosphorescence lifetimes, emission‐wavelength covering the whole entire visible range, high luminescence efficiency. [ 30–35 ] Among these heavy‐metallic complexes, ruthenium complexes have successfully been applied in confocal luminescence imaging, [ 36 ] time‐resolved photo‐luminescence detection [ 37 ] and ions recognition.…”
