Conjugated polymer semiconductors are of fundamental and technological interest for applications ranging from photovoltaic cells and integrated circuits, to biological sensors and fluorescent probes for bioimaging. The ability to engineer the electronic structures and properties of organic polymer semiconductors by molecular design and synthesis and elucidating structure–property relationships is essential for developing novel materials, functions and device applications. Also of significant interest is the synthesis of zero–dimensional (0–D) and one–dimensional (1–D) nanostructures of organic semiconductors for exploration of the effects of carrier and exciton confinements as well as applications in electronic devices, in vivo targeted imaging, and delivery of therapeutics. The first part of the seminar will focus on the design and synthesis of new classes of p– and n–type organic semiconductors, factors that determine their self-assembly into 1–D nanostructures, elucidation of structure–property relationships that govern their electronic and optoelectronic properties, and their application in field-effect transistors, light-emitting diodes, and solar cells. The second part of the seminar will detail recent efforts in developing multicomponent conjugated polymer nanoparticles as a highly fluorescent probe with tunable photophysical properties and a modular platform for detection of biological analytes, in vivo targeted imaging, and delivery of therapeutics for early diagnostics and treatments.
