摘要
合成了含β二酮(HTTA或HDBM)的稀土铕配合物Eu(OC3H7)xβy,并与MMA单体通过本体聚合获得PMMA/Eu(OC3H7)xβy聚合物,研究稀土配合物中x与y的大小对聚合物性能的影响.结果表明:PMMA/Eu(OC3H7)xβy聚合物能发射很强的Eu3+离子的特征荧光,其中当x=3(y=0)时,荧光强度最小,当y=2(x=1)时,荧光强度强且与y=3(x=0)时相当;x与y的大小对聚合物的溶解性及微观形貌都有一定的影响.
The europium complexes Eu(OC3H7)xβy containing β-diketone (HTTA or HDBM) were synthesized and the photoluminescent organic glass materials containing the complexes were prepared by bulk polymerization. The influence of molar ratios of isopropoxyl to β-diketone group on properties of the polymers was studied. The results show that the organic glass materials with Eu(OC3H7 )xβy exhibit strong characteristic luminescence of Eu^3+ ion under proper excitation. The luminescent intensity of the polymer containing Eu(OC3H7)3 is the lower,whereas the luminescent intensity of the polymer containing Eu(OC3H7)β2 is as high as that of Euβ3. Moreover, the solubility and micromorphology of the polymers vary with molar ratios of isopropoxyl to β-diketone group.
