Spectrum Chemicals Australia Charge transfer complexes for organic metals exhibit metal-like electronic behavior and have resulted in very intensive studies of these organic metals. The charge transfer complex consists of an electron donor and an electron acceptor. Charge-transfer complexes exist in many types of molecules, inorganic as well as organic, and in all phases of matter, i.e. in solids, liquids, and even gases. This section presents a variety of electron donors and acceptors. contact us.
