Product Details of 27828-71-3. The reaction of aromatic heterocyclic molecules with protons is called protonation. Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms. Compound: 5-Hydroxynicotinic acid, is researched, Molecular C6H5NO3, CAS is 27828-71-3, about Construction of a novel 2D Pb(II)-Organic framework: Syntheses, crystal structure, and property. Author is Jin, Feng.
Metal-organic frameworks (MOFs) have been widely explored and investigated as inorganic-organic hybrid materials for lots of scientists, which is not only due to their broad applications but also their various structures. Herein, a novel 2D Pb(II)-organic framework (complex 1) was successfully synthesized by heating 5-hydroxynicotinic acid (HL) and Pb(NO3)2 in a mixed solution of MeCN and H2O. The as-synthesized sample was measured by various characterization analyses, including elemental anal. of C, H, and N, single-crystal x-ray diffraction, powder x-ray diffraction, scanning electron microscope, and thermal gravimetric anal. More importantly, complex 1 can be considered as a high-efficient luminescent sensor for Fe3+ with good recyclability and high selectivity. And the Ksv value of complex 1 to Fe3+ was calculated to be ∼4.7 x 103 M-1. Thanks to the stability and Pb(II) centers as Lewis acid sites, complex 1 has a potential application as a heterogeneous catalyst for the CO2 cycloaddition reaction with preferable recyclability.
