Use of rhodamine-allyl Schiff base in chemodosimetric processes for total palladium estimation and application in live cell imaging

Rhodamine derivatives are excellent fluorescent probes and have shown sharp descending trends of emission intensity on interaction with specific analytes, which causes opening of the spirolactam ring. In this study, rhodamine-allyl Schiff base ( RD-2 ) is used as a highly sensitive colorimetric and...

Description
Summary:Rhodamine derivatives are excellent fluorescent probes and have shown sharp descending trends of emission intensity on interaction with specific analytes, which causes opening of the spirolactam ring. In this study, rhodamine-allyl Schiff base ( RD-2 ) is used as a highly sensitive colorimetric and fluorescent chemosensor for total palladium determination, and is indifferent to oxidation states (0, ii , iv ). The LOD is 95 nM. In addition, it is also a brilliant sensor for in vitro imaging of Pd 2+ in RAW 264.7 (macrophage) cells. The probe RD-2 is structurally characterised by single-crystal X-ray diffraction measurement.
