Summary

The previous chapter dealt with so-called symmetrical sandwiched metallocenes. In addition to these more traditional symmetrical metallocenes, a wide variety of metal-containing macromolecules exist where the metal is bonded to a lone ring system or to an asymmetrical sandwich-like system. As in the case of the symmetrical metallocenes, attachment of the metal is via π or π-type bonding. Here, the metal is normally not part of the backbone but rather resides directly adjacent (pendent) to the backbone or is further removed from the backbone within side chains. The metal can be uncharged or present as a cation. Introduction of the metal-containing moiety has been achieved using all of the traditional synthetic routes. Metal carbonyls are often chosen as the metal-containing moiety for single ring systems. Generally, the metal-containing moiety is introduced in the polymer forming step, but there are ample examples of the metal being introduced to already-formed polymer systems. Some polymers have been produced using supramolecular assembly. Some appear as part of star, sheet, and dendrite structures.
