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)₁₂O₁₄(OH)₆}²⁺, which is prepared by hydrolysis of butyltin triisopropoxide, 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.¹³C and¹¹⁹Sn NMR, in the solid state, and QELS evidences of the formation of hybrid organic-inorganic copolymers are reported.
