Organometallic Materials and Polymers

Inorganic chemistry provides many of the materials—from concrete to silicon chips—that are indispensable to modem life. The need for designed materials with special properties will continue to grow in the new century. Oiganometallic chemistry is beginning to contribute in several ways. For example, in metal organic chemical vapor deposition (MOCVD). a volatile metal compound is decomposed on a hot surface to deposit a film of metal. A typical example is the use of Cr(C6H6)2 to deposit Cr.  

An applied voltage injects electrons and holes into the material, and when these find each other, energy is emitted that corresponds to the HOMO-LUMO gap of the molecule. Cyclometalated iridium(UI) complexes, such as 12.19-12.21, have proved very effective in allowing the emission wavelength to be tuned by variation of the structure.
