研究领域

Organic/Materials/Synthesis of Highly Conjugated Polymers/Organic Diradicals and Polyradicals/Crystal Engineering/Organic Photovoltaics/Energy Transfer in Organic Conjugated Multichromophores

Combining theoretical, synthetic, and physical chemistry to study the electronic properties of molecules, polymers, and molecular materials has been the focus of my group's work. All of our work has involved the understanding and electronic properties from a physical organic and materials point of view.
