This project will design and synthesize novel conjugated polymers with donor-acceptor structures for the development of novel building blocks and polymer systems. Substituent groups will be introduced into the donor and acceptor units to enhance solution-processing ability and to ensure high charge carrier transporting properties. The performance of polymer semiconductors can be controlled by tuning intramolecular and intermolecular interaction. The purpose of the project is to obtain polymer semiconductors with excellent performances. We will modify both the surfaces of the source/drain electrodes and insulators, develop modification technology of interfaces, and fabricate high-performance field-effect transistors with a high mobility of 15 cm^2/V.s. Furthermore, we will systematically investigate the transporting mechanism of charge carriers, acquire a better understanding the relationship between molecular/aggregation structures and carrier transporting properties, and obtain innovative achievements with proprietary intellectual property rights. Therefore, this project is a prospective cross-cutting research subject with exploratory, possessing both scientific research and potential industrial applications.
