Hybrid organic-inorganic copolymers based on oxo-hydroxo organotin nanobuilding blocks

Hybrid organic-inorganic copolymers have been prepared following the nano-building blocks approach. The oxo-hydroxo butyltin macro-cation, {(BUSn)(12)O-14(OH)(6)}(2+), which is prepared by hydrolysis of butyltin tri-isopropoxide, is first functionalized by anchoring onto it methacrylate groups through electrostatic interactions. Then, to turn these isolated nano-building blocks into hybrid copolymers, they were assembled by initiating the organic polymerization of the methacrylate functions. C-13 and Sn-119 NMR, in the solid state, and QELS evidences of the formation of hybrid organic-inorganic copolymers are reported.
