Application of Functional Polymers Based on Multiple-Point Hydrogen Bonding( I )
子排列行為(block copolymer-like clusters)，至今仍存在許多的挑戰。因此，我們
In this project, we propose a new series of multiple hydrogen-bonded polymers and discuss the self-assembly behaviors by adjusting the strength of supramolecular interactions. These new materials will be employed to several fields and results of all anticipated research topics are summarized in the following: (I) Supramolecular assembly of designed α-helical polypeptide-based nanostructures: The first year, we combined the well-defined macromolecular architectures of polyhedral oligomeric silsesquioxane (POSS) and polypeptide to generate polymeric building blocks having distinct 3-D shapes for the self-assembling of supramolecular structures. There remain many aspects of forming block copolymer-like clusters transferred from binding and recognition events in fundamental research into non-covalent systems. Hence, this system is focusing on the hydrogen bonding effect with concomitant changes in bulk and solution states and further understands the morphology and mechanism of polymer self-assembly. (II) Hydrogen-bonding in polymer/carbon nanotube blends: The second year, the utilization of multiple hydrogen bonding events between the fiber matrix and carbon nanotubes (CNTs) is promising for further improvement in electronic performance. In the last three years, we concentrated on multiple hydrogen bonded interactions. Therefore, we would like to extend our previous experience on supramolecular interaction to the area of polymer nanocomposites. In earlier stage, we focus on preparing a series of supramolecular polymer/CNTs and further investigations the influence of suramolecular concentration, dispersion, and hydrogen bonding in functionalized CNT composites. Recently, we will explore further applications in electronic device and metal ion adsorption. (III) Supramolecular π-conjugated materials: The third year, we would like to prepare DNA-based conjugated polymer and supramolecular POSS, respectively. These materials are able to interact with each other to form a star-like structure through complementary pairing and exhibits improved solution processing, optical and electroluminescence properties. In this project, now we would like to further extend our studies for applications in areas such as high performance light-emitting diode (LED) and flexible device. It would provide positive contribution on preparation of supramolecular conjugated polymer to serve as hole-transporting, light-emitting, hole-blocking, and electron-transporting layers in LED devices.
