Volume 12 reviews real world applications of organometallic compounds in a variety of areas including electronics, materials, optics, sensors and environmental chemistry. It provides a clear and comprehensive overview of developments and future trends in the field. Applications is a new volume that did not appear in COMC (1982) or COMC-II (1995) and as such is the essential reference text for any chemist or technologist who needs to use or apply organometallic compounds.
