摘要
合成了含铕的有机配合物Eu(TTA)_2AA,并与乙烯基咔唑(NVK)进行共聚合反应,获得了Eu(TTA)_2AA-NVK共聚物。采用红外光谱、紫外光谱、荧光光谱、元素分析、ICP、DSC、动态激光光散射等手段对其结构进行表征。同时发现,含铕共聚物的荧光强度随Eu含量的增加而增加,未出现浓度猝灭现象。通过XRD进行分析研究发现,Eu(TTA)_2AA能够均匀地分散在共聚物中,并表现出强的荧光特性。
A europium polymer complex(Eu(TTA)_2AA-NVK)was successfully prepared via copolymerization between organic complex containing Eu(Eu(TTA)_2 AA),which was synthesized via the reaction among EuCl_3,TTA and AA,and NVK.Eu(TTA)_2 AA-NVK was characterized by the methods of IR,UV,ICP,DSC,EA,DLS and fluo- rescence spectra.Compared with the adulterated polymer(Eu(TTA)_2 AA/PVK),the fluorescence intensity of copoly- met Eu(TTA)_2AA-NVK increased upon increasing the concentration of Eu and there was no concentration que...
