|Abstract||A review. A no. of synthetic routes was utilized in the prodn. of organometallic monomers and polymers contg. arenes coordinated to the Group VI, VII and VIII transition metals. Transition metal-coordinated monomers were prepd. either by nucleophilic arom. substitution reactions of transition metal-coordinated haloarenes with phenolic compds. or via ligand exchange reactions. These monomers were polymd. directly or following removal of the metallic moieties to produce the resulting organometallic or org. polymers. Well-defined oligomeric ethers prepd. via sequential nucleophilic displacement reactions were functionalized via nucleophilic addn. reactions. Synthesis and characterization of heterometallic oligomers and complexes contg. both neutral and cationic metallic moieties are also reviewed. Synthesis of polymers contg. arenes coordinated to transition metal moieties was investigated using metal-mediated reactions. Introduction of transition metal moieties into pre-existing polymeric materials has also proven to be an effective methodol. to isolate this class of organometallic polymer. Supramol. assembly of arene complexes of transition metals was explored as a route to macromol. materials. Use of arene complexes has allowed for the prepn. of a no. of polyfunctional mols. used in the design of dendrimers and star polymers. [on SciFinder(R)]|
