Highly sensitive chemosensor for detection of PPi with improved detection limit

Anion recognition and sensing with Zn(ii)–dipicolylamine complexes

“…52 Compound 34 exhibits a large decrease in fluorescence intensity upon binding to PPi (9.8-fold) in 10 mM HEPES buffer (pH 7.4) at 25 1C, but a 4.8-fold decrease in fluorescence emission was also observed upon addition of ATP. On the other hand, other anions, including H 2 PO 4 À , AMP and ADP do not induce detectable fluorescence changes.…”

ZnII Complexes for Bioimaging and Correlated Applications

“…As a result, several fluorescent probes have been designed for the PPi detection. These fluorescent probes are primarily supramolecular receptors based on either ensemble of Zn II complexes or organic compounds with cautious optimization of non‐covalent interactions …”

Delivery modulation in silica mesoporous supports via functionalization in the pore outlets with a Zn(II)–bis(2-pyridylmethyl)amine complex

“…In fact the interaction of Zn(II)-dipicolylamine complexes with both organic and inorganic phosphates is well documented and for instance has been extensively used for the preparation of selective fluorogenic probes for these anions. [68][69][70][71][72][73][74][75][76][77] Moreover, in order to test the effect of the concentration of the anions on the [Ru(bipy) 3 ] 2+ dye release behavior of the SZn material additional experiments were carried out using anions at a concentration of 1.0 x 10 -2 mol L -1 . In this case nearly the same inhibition trend for solid SZn was observed (vide infra).…”

“…In fact phosphate has been reported to display a high affinity for Zn(II)-3-like complexes. [68][69][70][71][72][73][74][75][76][77] Moreover the effect of the anion size (and charge, vide infra) can be observed when the anion series phosphate, pyrophosphate, AMP, ADP or ATP is compared. In this case all these anions have been reported to form complexes with Zn(II)-3-like complexes and the different cargo release is related with their different size; i.e.…”
