Integrating Contorted Aromatic Molecules into Molecular Electronics and Optoelectronic Devices
This thesis has focused on the optical and electronic properties of organic semiconductors and their application in molecular electronic and optoelectronic devices. The studies have featured new and useful properties from a series of perylene diimide (PDI) nanoribbons and conjugated macrocycles. These novel strained carbon-based materials are highly promising as n-type semiconductors in organic gas sensor, organic solar cells and organic photodetectors. In Chapter 2, I describe a new molecular design that enables high performance organic photodetectors. We use a rigid, conjugated macrocycle as the electron acceptor in devices to obtain high photocurrent and low dark current. We make a direct comparison between the devices made with the macrocyclic acceptor and an acyclic control molecule; we find that the superior performance of the macrocycle originates from its rigid, conjugated,...
