Organometallic chemistry is an interdisciplinary field that is diverse both in its study and applications. Topics investigated academically include the synthesis and reactivity of new transition-metal complexes, the creation of catalysts for new organic transformations, the activation of small molecules such as dinitrogen, and the search for alternative energy sources. Industrial applications are manifold, with organometallic catalysts used for the manufacture of polymers, pharmaceuticals, and fine chemicals, while organometallic complexes are incorporated into OLEDs for displays in consumer electronics. The awarding of the 2001 and 2005 Nobel Prizes was a clear manifestation of the continued importance of organometallic chemistry.
