A novel phthalimide-rhodol-based ESIPT-FRET system for rapid colorimetric and ratiometric fluorescent detection of palladium

A highly sensitive sensor for colorimetric detection of palladium(ii) in lysosomes and its applications

“…In recent years, fluorescent probes have been widely used for palladium species detection due to their simplicity in implementation, low detection limit and real-time detection in living cells. 6 To date, a variety of fluorescent probes have been developed to detect palladium based on the complexation of palladium with the receptors; 7 however, the coordination mechanism easily suffers interference from other metal ions. Therefore, a generally useful strategy for designing fluorescent probes for palladium detection is to functionalize the fluorophore with a palladium recognition unit.…”

A Near-infrared Fluorescent Probe of Dicyanoisophorone Derivatives for Selective Detection and Fluorescence Cellular Imaging of Palladium

“…In recent years, the development of fluorescent probes has made it possible to visually detect some heavy metal ions such as Hg 2+ , Cr 3+ and Cu 2+ and gas molecules. [12][13][14][15][16][17][18][19][20] Fluorescent probes for palladium ions are mostly constructed based on palladium-based catalysis or coordination. Besides, based on the Tsuji-Trost reaction catalyzed by Pd (0), several fluorescence-enhanced probes have been developed that could selectively detect Pd (0).…”

A novel ratiometric AIEE/ESIPT probe for palladium species detection with ultra-sensitivity

“…12 On the contrary, probes based on a catalytic mechanism usually show superior selectivity. [13][14][15][16][17][18][19][20] However, we noticed that some limitations still exist in the detection of palladium based on catalytic mechanism, such as long detection times and detection difficulty in extremely low concentrations. [21][22][23][24][25] In addition, most uorophores of uorescence probes exhibit relatively small Stokes shis, which hinders their applications in quantitative determination due to self-absorption.…”

“…[21][22][23][24][25] In addition, most uorophores of uorescence probes exhibit relatively small Stokes shis, which hinders their applications in quantitative determination due to self-absorption. 18,[26][27][28] Moreover, many probes detect OFF-ON or ON-OFF signal output changes in their uorescence intensity. This type of probe with a single uorescence change could be signicantly inuenced by environmental effects, along with a decrease in signal delity.…”
