研究领域

We are particularly interested in the molecular assembly processes during solution printing of organic functional materials, such as flexible electronics and solar cells etc. Solution printing is en route to transform the ways advanced materials are made, bringing closer an energy-efficient, eco-friendly and personalized future of manufacturing. A key challenge to realizing this future lies in the control of molecular assembly processes during solution printing – a highly non-equilibrium process. The solid-state properties are highly sensitive to molecular packing, morphology and architecture of printed materials. We draw upon knowledge from surface science, nanotechnology, fluid dynamics, X-ray science, physical chemistry, etc to gain new insights and to develop novel methods for controlling molecular assembly processes. A reoccurring theme in my group is the design of structured interfaces across multiple length scales for controlling molecular assembly. At different length scales, the surface structures “converse” with assembling molecules in entirely different “languages”, and thereby directing molecular packing and morphology to influence solid state properties by orders of magnitudes. To decipher the complex structures of molecular assemblies, we employ a combination of characterization methods. In particular, X-ray based techniques offer valuable insights spanning from micro- to macro-scopic scales. In addition, we probe the dynamics of molecular assembly processes using state-of-the-art in situ X-ray scattering techniques.
