Metal atoms have been incorporated into macromolecular structures utilizing σ bonding. While the “primary” bonding occurs via σ bonding, π bonding is also often present. The metal may be attached to the macromolecular structure via σ bonding to (most commonly) carbon, oxygen, nitrogen, and sulfur as well as metal to metal bonding. Again, the formation of σ-bond linkages has been accomplished through a wide range of reactions including addition and condensation. Many of these materials show non-linear optical, electrical conducting and semi-conducting, and liquid crystal properties. As with many of the other metal-containing polymers, there is an emphasis in the creation of star and dendrimer structures generally because such structures may allow the metal-atom sites to function somewhat independently for various purposes such as catalytic and sensing.
