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.
