Recently, a class of open-shell macromolecules has been identified in which novel ground state and low-energy electronic properties have been identified. Beyond their paramagnetic character, very little about basic quantum mechanical properties of open shell polymers has been described.
Matthew Sfeir studies a series of closely related polymers that have been identified as having a paramagnetic ground state using time-resolved optical, terahertz, and microwave electromagnetic probes. He aims to articulate how macroscopic properties such as conduction, magnetism, and broad infrared absorption emerge from the coupled microscopic quantum degrees of freedom.
Dr. Sfeir aims to facilitate new scientific capabilities and performance in organic electronic devices, with potential use cases in optomechanical and optoelectronic devices, as sensors for the local chemical environment, and as photochemical reaction centers. New materials with both high electrical conductivity and additional novel functionalities are needed to meet the emerging needs of advanced photonic and quantum-based technologies.
