Hybrid materials doped with novel europium complexes were synthesized using PMMA-co-Sn(12)Clusters (copolymers from oxohydroxo-organotin dimethacrylate and methylmethacrylate) as the matrix material. Two types of hybrid materials were obtained: the physically doped product, PMMA-co-Sn(12)Cluster/Eu(TTA)(3)phen, and the grafted product, PMMA-co-Sn(12)Cluster-co-[EuAA(TTA)(2)phen] (TTA = 2-thenoyltrifluoroacetone, phen = phenanthroline and AA = acrylic acid). The hybrid materials exhibited characteristic luminescence of the Eu(3+) ions, and also showed relative especial optical properties compared with samples just using PMMA as the matrix material. The PMMA-co-Sn(12)Cluster matrix exhibited a high physical doping quantity of [Eu(TTA)(3)phen], which can be attributed to the special structure of this kind of hybrid material. GPC (gel-permeation chromatography), TGA (thermogravimetric analysis), SEM, (1)H NMR, ICP (inductively coupled plasma), (119)Sn NMR, FTIR, and diffuse reflectance techniques were employed to characterize the structures and properties of these hybrid materials.
采用 PMMA-co-Sn(12)Clusters（由氧羟有机锡二甲基丙烯酸酯和甲基丙烯酸甲酯共聚而成的共聚物）作为基质材料，合成了掺杂新型铕配合物的杂化材料。得到了两种类型的杂化材料：物理掺杂产物 PMMA-co-Sn(12)Cluster/Eu(TTA)(3)phen 和接枝产物 PMMA-co-Sn(12)Cluster-co-[EuAA(TTA)(2)phen]（TTA = 2- 苯甲酰三氟丙酮，phen = 邻菲啰啉，AA = 丙烯酸）。杂化材料表现出 Eu(3+)离子的特征发光，并且与仅使用 PMMA 作为基质材料的样品相比，还表现出相对特殊的光学性质。PMMA-co-Sn(12)Cluster 基质具有高的[Eu(TTA)(3)phen]物理掺杂量，这归因于这种杂化材料的特殊结构。采用凝胶渗透色谱（GPC）、热重分析（TGA）、扫描电子显微镜（SEM）、（1）H NMR、电感耦合等离子体（ICP）、（119）Sn NMR、傅里叶变换红外光谱（FTIR）和漫反射技术对这些杂化材料的结构和性质进行了表征。
