Abstract

The rapid development of conjugated polymeric materials has enabled the organic electronic and optoelectronic devices technology (organic field effect transistors, organic solar cells, organic light-emitting diodes, and organic thermoelectric devices) to develop at a rapid pace in the last decades. In order to make these devices suitable for practical applications, stable and efficient devices are required. This also demands new materials with superior properties such as outstanding charge transport, and a high chemical and mechanical stability. Thus, fundamentally understanding the structure-properties relationship is the key to designing new materials for these devices.
The scientific goal of this thesis aims to use chemistry approaches to design novel conjugated polymers for specific purposes: 1) enhancing the solubility of intrinsic conjugated polymers in green solvents to replace the highly toxic chlorinated solvent in fabricating organic electronic devices; 2) design and synthesis of n-type conjugated polymers in pursuit of high performance organic thermoelectric devices and for better understanding of the relationship between chemical structures and device performances; 3) investigating novel polymerization strategies to make conjugated polymers. In the meantime, we are also interested in understanding the relationship between the molecular structures and charge transport in single-molecular and molecular-ensemble monolayer tunneling junctions.
