This class introduces the broad field of functional materials and their applications to the undergraduate students. It is designed for undergraduate students who have been expose to organic/polymer chemistry, physics as well as materials science, and wish to have a basic understanding of functional organic materials. The main purpose is to reveal basic concepts and general knowledge associated with the synthesis and applications of organic materials with bioscience, energy and sensing applications; clearly elucidate structure and function relationships, and to employ various characterization techniques to determine materials structure and order at various length scale.
