Welcome to the website of Professor Yang’s group. Our laboratory, Organic Optoelectronic Polymer Laboratory, was established in February, 2010. Our research projects mainly concerns the development of new functionally fluorescent materials for use as emissive or charge transport materials in organic electronic devices, such as chemosensors and storage systems. Research involves the synthesis and characterization of novel fluorescent materials, including fluorene, carbazole, and triphenylamine-based compounds as electron donor unit or 2,1,3-benzothiadiazole (BT) and diketopyrrolopyrrole (DPP)-based compounds as electron acceptor unit with high quantum yield, excellent thermal and oxidative stability, and convenient color tenability. We also synthesized amphiphilic diblock polymers containing azobenzene moieties and we study their corresponding phase separation in various amounts of THF/water mixture via self-assembly. Students who join in our laboratory can learn how to synthesize organic materials, to purify/ identity the structure of the synthesized materials using FT-IR, NMR, EA, Mass, UV, PL, XRD, CV, and Gaussian techniques. They can also realize the viewpoint and concept of organic optoelectronic field. We are seeking students interested in optoelectronic polymers to join our group.
