New luminescent lanthanide centered Si-O-Ti organic-inorganic hybrid material using sulfoxide linkage

摘要

A new sort of chemically bonded lanthanide organic-inorganic hybrid material has been constructed through the bifunctional sulfoxide molecular bridge (MSAPSi, which is functionalized 2-(methylsulfinyl) acetophenone (MSAP) by 3-(triethoxysilyl)-propyl isocyanate (TESPIC)) linking Si-O-Ti-0 inorganic networks. The results suggest that the obtained hybrid materials are totally amorphous without phase separation phenomenon and exhibit the characteristic luminescence of Eu~(3+) and Tb~(3+) ions. Furthermore, the decay times and emission quantum efficiency of Eu~(3+) hybrid material are also determined.
