摘要
采用成核/晶化隔离法制备出和锌铝水滑石(Zn/Al-LDHs),并以其为反应前体(主体),以乙二醇为分散介质,分别采用返混/沉淀法和原位法将具有荧光吸收性能的肉桂酸(客体)引入CO32-型水滑石层间,制备出肉桂酸插层水滑石,利用红外光谱仪、荧光分光光度计等手段对样品进行了表征。结果表明,肉桂酸根可以取代锌铝水滑石前体层间的CO32-离子,组装得到结构良好的肉桂酸插层水滑石,其在300～400nm之间有良好的荧光吸收峰,具有一定的荧光效果。
Zn/Al hydrotalcite （Zn/Al-LDHs） were prepared by the nucleation/crystallization in this thesis. The einnamate-pillared hydrotalcites of Zn/Al-LDHs have been successfully assembled by returns mixes precipitation method and original place method in ethylene glycol. The samples were characterized by FTIR and means of fluorescence spectroscopy. The results showed that cinnamic acid radical can be substituted hydrotalcite, zinc and aluminum precursors hydrotalcite interlayer CO3^2-, are well-structured assembly of cinnamic acid hydrotalcites, cinnamic acid hydrotalcites has good absorption between 300 - 400nm, so it has good fluoresc.ence properties.
