Research Interests
Macromolecular Chemistry/Materials Chemistry/Organic Electronics/Supramolecular Chemistry/ Supramolecular Electronics
We have broad interests in materials science, specifically in areas such as macromolecular chemistry, electronic/photonic materials, supramolecular chemistry and responsive materials.
Functional p-systems: synthesis and applications for electronics
We are interested in the design, synthesis and materials applications of all kind of functional p-conjugated systems such as polymers, oligomers, dendrimers and polycyclic aromatic hydrocarbons (PAHs) with unique electronic / optical properties. These materials will be mainly used for electronic devices such as field effect transistors and solar cells. Our research is focused on molecular engineering to improve device performance. We have close collaboration with strong device engineering and materials physics teams. Specifically, we are interested in a kind of nano-sized graphene molecules and related structures, their synthesis, self-assembly and processing/device fabrication (see below).
2. Supramolecular architectures and smart materials
We are also interested in the design of novel supramolecular architectures and their materials applications. Our research is mainly focused on template-directed synthesis of various architectures such as rotaxanes, catenanes, molecular necklaces and supramolecular dendrimers, etc.. Switchable supramolecular systems will be used for smart materials such as artificial muscles, surface responsive materials, drug delivery and controlled drug release, gene delivery, etc…. (see below).
Finally, we hope to combine the knowledge and methods in supramolecular chemistry, organic chemistry, polymer chemistry and materials science and generate a new research area.
