Polymers have been traditionally used as electrically insulating materials: after all, metal wires are coated in plastics to insulate them. Various conjugated macromolecules with alternating single and double bonds can now be synthesized with unusual electrical and optical properties through the ?-electron delocalization along their backbones. Due to the molecular rigidity of conjugated backbones, however, most unfunctionalized conjugated polymers are intractable (i.e., insoluble and/or infusible). Nevertheless, a number of synthetic methods have been devised to produce conjugated polymers with the processing advantages of plastics and the optoelectronic properties of inorganic semiconductors for optoelectronic device applications, including polymer photovoltaic cells and polymer light-emitting diodes [1].
Having conjugated all-carbon structures, carbon nanomaterials, including carbon nanotubes (CNTs), graphene, and graphene-dots also possess certain similar optoelectronic characteristics as conjugated macromolecules, apart from their unique structures and associated properties (e.g., surface/size effects) [2]. With the rapid development in nanoscience and nanotechnology, various nanomaterials (e.g., nanocarbons, quantum dots, DNA, perovskites) have been playing a more and more important role in the development of efficient optoelectronics [2-4], along with energy conversion and storage devices [5-9]. The combination of the unique physicochemical properties of nanomaterials (particularly, graphitic carbon nanomaterials) with comparable optoelectronic properties of appropriate conjugated macromolecules has yielded some interesting synergetic effects.
In this talk, we will summarize our work on rational design and development of hybrid optoelectronics and energy conversion/storage devices based on conjugated polymers, graphitic carbons, and perovskites. A brief overview of this exciting field, along with some challenges and opportunities, will also be presented.
