We are committed to developing new controllable construction strategies and characterization methods for multicomponent and hierarchical assembly systems. From the perspective of non-covalent synthesis, we pay attention to the study of assembly moieties, conditions, process and products, develop a new efficient and accurate controllable assembly strategy – catassembly, develop in situ, real time and high resolution assembly characterization methods represented by the microfluidic NMR. In the micro and nano scale, we study the biomimetic communication network of complex assembly systems constructed via material, energy and information exchange. In the macroscopic scale, by combining big data and machine learning, we study the complex self-organization systems based on multi-mode communication mechanism.
