　　Understanding how complex hybrid materials are organized through synergistic self-assembly and chemical synthesis across extended and multiple length scale is of growing interest in materials science and technologies. This talk will highlight some recent advances in the synthetic construction of macroscopic bulk materials under equilibrium conditions. We focus on organization of higher-order architectures from inorganic nanophases using cellulose self-assembly to coordinate the nucleation, growth and transformation. We examine a range of synthetic modalities that give rise to extended length-scale organization of matter spanning from molecular to macroscopic level. Of particular interest is a helical superstructure of cellulose to facilitate its use as a functional nano-building block for extended-scale structuration with anisotropic properties and chiroptical activity. Key elements of the constructional codes associated with these processes are identified based on existing knowledge, and presented as a practical guideline for the organization of advanced nanomaterials that hold promising potentials in photonic, environmental and energy applications.

　　Yan Xu received her PhD from Imperial College London UK. She is currently a full professor in the State Key Lab of Inorganic Synthesis and Preparative Chemistry, Jilin University, China. She has coauthored two books, published over 80 papers in refereed scientific journals and holds three patents. Her current research interests seek to advance a new integrative approach to the synthetic construction of macroscale bulk materials with embedded complexity, higher-order architectures and integrated functions from multi-scale building blocks, and emergence of complex forms of organized matter.
