Polymorphism in Organic Semiconductors: Understanding the effects of nanoconfinement on molecular packing

Numerous organic materials have the ability to adopt different molecular packing states (polymorphs). In the proposed study, we will investigate organic semiconductors whose electronic and optical properties can be modulated by polymorphism over orders of magnitudes. We are working to provide new insight on how polymorphic states are influenced by the characteristics of nanoscopically confined environment, which is a geometry highly relevant to device applications, e.g. organic transistors.
