Manipulating the Spatial, Charge Transfer, and Energetic Interactions of Open Shell Moieties in Multifunctional, Low Glass Transition Temperature Radical Polymers
Abstract
Organic electronic materials have provided for next generation display technologies, and they offer the promise of advancing the state of the art in myriad other commercial and military applications due to their tunable optoelectronic properties, ready syntheses, compatibility with low cost manufacturing, and ability to be used in flexible and stretchable electronic platforms. To date, however, most organic electronic technologies have focused solely on the transport of energy and charge through small molecules and polymers. That is, many conventional organic electronic devices neglect the added high value functionality and potential end use operational benefits associated with the magnetic properties of organic materials and the opportunity to manipulate this functionality through the application of external fields. Additionally, the current archetype associated with organic electronic materials is focused on the design and implementation of closedshell materials that contain large degrees of conjugation in their molecular structures. In this effort, we directly challenge this design paradigm by introducing non conjugated macromolecules with magnetically active, open shell sites present along the pendant groups of the polymer chains. In this way, we envision being able to provide the design rules that will allow for novel macromolecules with never before seen magnetic field dependent properties. In order to address this overarching objective, we will: (1) computationally design monomers and macromolecules with promising properties; (2) synthesize organic electronic materials targeted from the computational design and characterize their resultant molecular and thermal properties; (3) control the nanostructure of the open shell macromolecules in the bulk and thin films states; and (4) implement these radical polymers in magnetic field dependent thermoelectric modules.
