The chemical properties of alicyclic heterocycles are similar to those of the corresponding chain compounds. Compound: Picolinoyl chloride hydrochloride, is researched, Molecular C6H5Cl2NO, CAS is 39901-94-5, about Ratiometric Fluorescent Sensor for Copper(II) and Phosphate Ions from Aminopyrene Derivatives, the main research direction is copper phosphate ion aminopyrene derivative ratiometric fluorescent sensor.HPLC of Formula: 39901-94-5.
Three derivatives of 1-aminopyrene are functionalized with 2-picolyl and 2-picolinyl groups and are tested as fluorescent sensors for metal ions. The target compounds are successfully synthesized in yields of 50-90% and characterized by 1H-NMR, 13C-NMR, and HRMS. The compound with an amino picolyl group (P1) exhibits an excellent selectivity toward Cu(II) ion as the fluorescent signal shifts from 433 to 630 nm. From a fluorescence titration experiment, the limit of detection for Cu(II) ion is estimated as 0.19 μm. The fluorescence spectral shift by Cu(II) ion is reliant on the use of acetonitrile as a co-solvent, and the results from cyclic voltammetry and UV-Vis spectroscopy suggest that the sensing mechanism involves a coordination complex between the P1, acetonitrile and Cu(II) ion. Furthermore, this P1-Cu complex can also be used as a selective fluorescent sensor for PO43- ion with a detection limit of 0.44 μm.
