This paper reviews work on the magneto-optical properties of π-conjugated polymers, in particular regioregular poly(3-alkyl)thiophenes. We give an overview of the theoretical formalism that led to the first observation of Faraday rotation from thin films of poly(3-dodecyl)thiophene and experimental results, which include Faraday rotation studies from thin films composed of various polythiophene derivatives with varying degree of regioregularity We also discuss possible correlations of Faraday rotation and the supramolecular organization within the thin films of these polymers. When appropriate, we point out possible applications or suggest directions for further research. Organic magneto-optic polymer materials could reduce production costs for various magneto-optic devices, as these materials are solution processable and amenable to roll-to-roll processing.
