The chemical properties of alicyclic heterocycles are similar to those of the corresponding chain compounds. Compound: Bis(acetylacetonato)dioxomolybdenum(VI), is researched, Molecular C10H14MoO6, CAS is 17524-05-9, about Sequential Fluorescence Recognition of Molybdenum(VI), Arsenite, and Phosphate Ions in a Ratiometric Manner: A Facile Approach for Discrimination of AsO2- and H2PO4-, the main research direction is sequential fluorescence recognition molybdenum arsenite phosphate ion ratiometric manner.Related Products of 17524-05-9.
An amide based smart probe (L) is explored for nano-molar detection of Mo(VI) ion in a ratiometric manner involving hydrogen bond assisted CHEF (Chelation Enhanced Fluorescence) process through inhibition of PET (Photoinduced Electron Transfer) process. The recognition of Mo(VI) is associated with 17-fold fluorescence enhancement and confirmed by single crystal X-ray diffraction (SCXRD) of the resulting Mo(VI) complex (M1). Further, M1 selectively recognizes arsenite through green emission of their adduct (C1) with 81-fold fluorescence enhancement. Interestingly, dihydrogen phosphate causes dissociation of C1 back to free L having weak fluorescence. The methods are fast, highly selective and allow their bare eye visualization at physiol. pH. All the interactions have been substantiated by TD-DFT calculations to rationalize their spectroscopic properties. The corresponding lowest detection limits are 1.5 × 10-8 M for Mo(VI), 1.2 x 10-10 M for AsO2- and 3.2 × 10-6 M for H2PO4-whereas resp. association constants are 4.21 × 105 M-1 for Mo(VI), 6.49 x 104 M-1 for AsO2- and 2.11 x 105 M-1 H2PO4-. The L is useful for efficient enrichment of Mo(VI) from aqueous solution while M1 efficiently removes AsO2- from environmental samples by solid phase extraction
