Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: Picolinoyl chloride hydrochloride, is researched, Molecular C6H5Cl2NO, CAS is 39901-94-5, about Synthesis and spectral properties of luminescent europium(III) and terbium(III) complexes with an amide-based, open-chain crown ether.Quality Control of Picolinoyl chloride hydrochloride.
A new amide-based, open-chain crown ether ligand, 1,7-bis(2-N-(2-pyridyl)-benzamide)-1,4,7-trioxaheptane, and its Eu(III) and Tb(III) complexes were synthesized and characterized. The Eu(III) and Tb(III) ions coordinate to the O atoms of the C=O and the N atoms of the pyridine rings. The fluorescence properties of these complexes in the solid state and DMF and MeOH/CHCl3 solutions were studied. Under the excitation of UV light, a very strong red fluorescence of the solid [Eu(NO3)2L](NO3) complex and a green fluorescence of the solid [Tb(NO3)2](NO3) complex were observed The solvent factors influencing the fluorescent intensity are also discussed.
In some applications, this compound(39901-94-5)Quality Control of Picolinoyl chloride hydrochloride is unique.If you want to know more details about this compound, you can contact with the author or consult more relevant literature.
