Synthesis and Optical Properties of Europium‐Complex‐Doped Inorganic/Organic Hybrid Materials Built from Oxo–Hydroxo Organotin Nano Building Blocks

Hybrid materials doped with novel europium complexes were synthesized using PMMA‐co‐Sn₁₂Clusters (copolymers from oxohydroxo‐organotin dimethacrylate and methylmethacrylate) as the matrix material. Two types of hybrid materials were obtained: the physically doped product, PMMA‐co‐Sn₁₂Cluster/Eu(TTA)₃phen, and the grafted product, PMMA‐co‐Sn₁₂Cluster‐co‐EuAA(TTA)₂phen] (TTA=2‐thenoyltrifluoroacetone, phen=phenanthroline and AA=acrylic acid). The hybrid materials exhibited characteristic luminescence of the Eu³⁺ ions, and also showed relative especial optical properties compared with samples just using PMMA as the matrix material. The PMMA‐co‐Sn₁₂Cluster matrix exhibited a high physical doping quantity of Eu(TTA)₃phen], which can be attributed to the special structure of this kind of hybrid material. GPC (gel‐permeation chromatography), TGA (thermogravimetric analysis), SEM, ¹H NMR, ICP (inductively coupled plasma), ¹¹⁹Sn NMR, FTIR, and diffuse reflectance techniques were employed to characterize the structures and properties of these hybrid materials.
