Organic magnetic materials: an overview

The findings of organic materials for electroluminescent devices has opened the door for a wide variety of applications in displays, communications, sensors, and the like. The advent of creating organic electromagnetic materials has raised the challenge of finding polymer (organic) materials in which there is sufficient electronic exchange as well as stability in both the thermal and chemical arena. 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 superparamagnetic materials for devices of the future in power, storage, displays, and communication devices. The use of these methods to produce ferri-, para-, and superparamagnetic materials has changed our way of thinking about how to fabricate magnetic devices with properties heretofore unrealizable. The underlying principles and formulations of molecular structures which either imitate conventional ferromagnetic materials or uniquely take advantage of the complex molecular magnets offered by organic materials are described. New materials which introduce large numbers of magnetically coupled spins are explained
