Preparation and Characterization of Pyridoxal hydrazide Modified Novel Luminescent Metal-Organic Frameworks
摘要
Abstract
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 molecule of pyridoxal hydrazide (PAH) which could recognise Cu2+ selectively on the surface and pore of ZIF-8.The morphology and structure of as-prepared PAH/ZIF-8 composites were characterized by nuclear magnetic resonance (1H CNR,13C NMR),fourier transform infrared spectroscopy (FT-IR),Xray 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.关键词
