| 摘 要： | 合成了聚N-异丙基丙烯酰胺（PNIPAAm）与Mn^2＋的配合物，并用荧光光谱、紫外-可见光谱及FTIR进行了初步表征。光谱数据说明Mn^2＋与PNIPAAm羰基氧发生了配位键合作用。由于Mn^2＋的发射光谱与PNIPAAm激发光谱部分重叠及Mn^2＋位于561nm的发射峰在Mn^2＋-PNIPAAm体系发射光谱中消失，说明发生了较好的Foerster能量传递。Mn^2＋-PNIPAAm配合物体系在307nm紫外区荧光强度比PNIPAAm增强了314％。

| Abstract: | The interaction of Mn2+ and poly (N-isopropylacrylamide) (PNIPAAm) was studied by using UV-Vis, FTIR and fluorescence spectroscopic methods. The results indicated that Mn2+ could be bonded to oxygen atoms of carbonyl in PNIPAAm and form the complex of Mn2+ -PNIPAAm. It was found that there existed efficient F?rster energy transfer from Mn2+ to PNIPAAm due to the emission spectra of Mn2+ overlapping the excitation spectra of PNIPAAm and that the emission peak of Mn2+ at 561 nm disappeared in Mn2+ -PNIPAAm complex. Therefore the fluorescence intensity at 307 nm was increased by 314%. |
