Electrically and Magnetically Active Polymers: Not Just Insulating Plastics James V. Masi Western New England College (emeritus) Springfield, MA 01119, 413-782-1272,

Abstract: The advent of organic materials for electroluminescent devices has allowed a wide variety of applications in displays, communications, sensors, and the like. The demonstration of organic magnetic materials has offered the challenge of finding polymer (organic) materials in which there is sufficient electronic exchange as well as stability in both thermally and chemically. The intrinsically conductive and semiconductive polymers have allowed designers the liberties of flexibility and conductivity to meet needs from batteries to solar cells. This paper gives an overview of this search past, present, and future and the synthesis of promising new complex polymer building blocks which can yield conductive, semiconductive, luminescent, ferro-, ferri-, and super-paramagnetic materials for devices of the future in power, storage, displays, and communications devices. The use of these materials to produce electrically active polymeric materials has changed our way of thinking about how to fabricate devices with properties heretofore unrealizable. There are three laboratory exercises described in this paper. They have been given both as in-class demonstrations and as student laboratories.

Molecular Magnetic Materials When the early civilizations made the discovery that iron was indeed attracted to lodestone, the era of magnetism and its devices and effects was launched. After that time, the earliest device recorded was the compass, an invention of the Chinese. Since then, ferromagnetic (Fe, Ni, Co, etc.), ferrimagnetic (e.g. F3O4), and paramagnetic materials have been used in technology applications such as magnets, magnetic tapes and disks, magnetic resonance imaging contrast enhancers, and magneto-optic memories, to name a few. Organic/molecular based materials, with p or d orbitals aiding the magnetic properties, have been a source of scientific curiosity for a number of years1,2, but only recently have such materials become a reality3,4,5. This new class of magnetic materials is, for the most part, non-metallic, being made from simple to complex organic molecules. Their structure can be uni- or bi-dimensional and need not have the three- dimensional format necessary for conventional ferromagnetic, ferrimagnetic, paramagnetic, and antiferromagnetic materials. These materials can be simply fabricated from a variety of solvents at or near room temperature. These should not be confused with bimetallic complexes such as those formed by pyrolisis or partial oxidation.6 Other work postulated the use of a new class of
