Hybrid Organic-Inorganic Materials Based on Nanobuilding Blocks Assembled through Electrostatic Interactions

摘要

Hybrid copolymers have been prepared by free radical polymerization,in toluene,of methy-lacrylate (MA) and varying amounts of an organotin oxo-cluster functionalized with two acrylamido groups,{(BuSn)_(12)O_(14)(OH)_6}(AMPS)_2.The tin based nanobuilding block is fully preserved in the final materials.These copolymers formed networks where the cross-linking is based on the electrostatic interactions that take place between the macrocation {(BuSn)_(12)O_(14)(OH)_6}~(2+) and its two functional anions (AMPS~-).Accordingly,these copolymers can yield gels or solutions depending on the solvent used to swell them.
