Helical Conjugated Polymers with Magneto-Optic Properties

The Faraday effect, is a ubiquitous magneto-optic (MO) effect, describing the rotation of the plane-polarized light traveling through a material along the axis of an applied magnetic field. While traditional MO materials are inorganic in nature, new generations of MO materials based on organic semiconducting polymers could allow increased versatility for device architectures, manufacturing options, and flexible mechanics. We are aiming at understanding the intrinsic molecular magnetism in these materials, and to expand the design space for organic MO materials.



Polymer magnetism in Semiconducting Conjugated Radical Polymers

Polymer magnetism is both promising and challenging. Investigations of molecular magnetism in radical polymers date back to 1980s, wherein cooperative magnetic phenomena arising from spin conduction through chemical bonds and ferromagnetism in organic materials were proposed. Investigations of magnetism in electronically coupled polyradicals have largely focused on applications in photonic and magnetic devices, wherein radical polymers were found to possess molecularly tunable and cooperative magnetic properties. We developed 1,3-bisdiphenylene-2-phenylallyl (BDPA)-based conjugated radical polymers that display ambipolar redox activity, superior conductivity and Faraday effect.
