Immobilized chloro complex

Immobilization of Organorare-Earth Metal Chloro Complexes... 

Early studies of the supported metal complexes utilized as hydrosilylation catalysts focused on the immobilization of H2PtCl6 on ion exchangers. Chloro-platinic acid and other Pt complexes have been used as efficient precursors of the catalysts anchored onto silica or organic materials for the hydrosilylation of 1-alkenes, styrene, allyl derivatives, and acetylene (3). 

Bipyridyl complexes of Ru(II) can be used for the production and storage of multiple photochemical redox equivalents by attachment to a soluble polymer. The photoactive complexes have been bound to a styrene/chloromethylstyrene copolymer by nucleophilic displacement of the chloro groups from the chloromethyl-styrene. Because the excited state properties are relatively unaffected in the mixed-valence polymers, it is possible to build up a chain of approximately 30 oxidative equivalents with a (bpy)2Ru or a (bpy)20s moiety bonded to each strand of the polyma . Excited state donors and acceptors can also be immobilized using a sol-gel technique. Such a technique has been s plied to the 1,4-dimethoxyl-benzene mediated photoinduced electron transfer between bipyridyl complexes of ruthenium and iridium. Metallopolymeric films have also been used for energy...
