A highly potential acyclic Schiff base fluorescent turn on sensor for Zn2+ ions and colorimetric chemosensor for Zn2+, Cu2+ and Co2+ ions and its applicability in live cell imaging
A novel pyrene based free thiol containing a Schiff base derivative PT1 was synthesized and reported as a fluorescence turn-on sensor for Hg2+ ions, via CHEF and excimer (PT1-PT1*) formation with live cell imaging.
Allylether-Rhodamine selectively invites Pd2+from mixture of other cations and Pd(0) in H2O-MeCN medium and exhibits maroon emission due to C(allyl)-O bond cleavage and opening of spirolactam ring. The LOD is 50 nM at pH 7. Imaging Pd2+species in living cells under physiological conditions is achieved.
