HYBRID ORGANIC-INORGANIC COPOLYMERS BASED ON OXO-HYDROXO ORGANOTIN NANOBUILDING BLOCKS

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