摘要
用红外光谱、X射线衍射谱及扫描电镜分析研究了合成温度对水杨醛缩乙二胺锌荧光性能的影响,结果表明,低温下合成的水杨醛缩乙二胺锌主要以单体形式存在,合成温度提高,通过酚氧桥键形成低聚体,合成温度提高,聚集程度增加,聚集状态不同,导致晶体结构及电子结构变化,从而引起荧光性能的变化。
The influences of synthesis temperature on fluorescence properties of (N,N'-bis(salicylidene)-ethylenediamin) zinc (Zn(salen)) were investigated. The causes of the fluorescence change of Zn(salen) were analyzed by IR spectra, XRD and SEM. The results show that Zn (salen) formed monomers at low synthesis temperature and formed oligomers via bridging oxygen atoms at higher temperature. The different oligomers result in different crystal stacking and different electronic structure, thereby affect its fluorescence properties.
