The metal-organic frameworks (MOFs) of zeolitic imidazolate framework-8 (ZIF-8) were assembled by hydrothermal method, and a novel luminescent MOFs was prepared by modifying luminescent organic mol. of pyridoxal hydrazide (PAH) which could recognize Cu2+ selectively on the surface and pore of ZIF-8. The morphol. and structure of as-prepared PAH/ZIF-8 composites were characterized by NMR (1H CNR, 13C NMR), Fourier transform IR spectroscopy (FT-IR), X-ray powder diffraction (XRD) and scanning electron microscope (SEM). The average diameter of the spherical PAH/ZIF-8 was 82 nm and it had fluorescence emission at 473 nm under the excitation of 354 nm, in addition, The fluorescence of PAH could be quenched in the presence of Cu2+ based on the coordinative complex formation between PAH and Cu2+, so the PAH/ZIF-8 will be a potential candidate for Cu2+ sensing. This study involved multiple reactions and reactants, such as 3-Hydroxy-5-(hydroxymethyl)-2-methylisonicotinaldehyde hydrochloride (cas: 65-22-5Reference of 65-22-5).
3-Hydroxy-5-(hydroxymethyl)-2-methylisonicotinaldehyde hydrochloride (cas: 65-22-5) belongs to alcohols. Under appropriate conditions, inorganic acids also react with alcohols to form esters. To form these esters, a wide variety of specialized reagents and conditions can be used. Tertiary alcohols cannot be oxidized at all without breaking carbon-carbon bonds, whereas primary alcohols can be oxidized to aldehydes or further oxidized to carboxylic acids.Reference of 65-22-5
