1. Chirality Transfer in Self-assembly of Block Copolymers and Homopolymers（文韬博士）

       内容摘要：The significance of chirality transfer is not only involved in biological systems, such as the origin of homochiral structures in life, but also in man-made chemicals and materials. In this talk, the transfer behavior of chiral bias, from molecular level to helical superstructure or phase, in the self-assembly of block copolymers and homopolymers will be described. In particular, we will discuss the controlling of hierarchical chirality of self-assembled superstructures, by means of chemical and physical concepts. In the first part, we will talk about the regulating of self-assembled morphologies of block copolymer with optical activity, via tailoring the chain chemical and topological structures. In the second part, the controlling of helicity of twisted lamellae for non-chiral polymer by induced circular dichroism (ICD) will be introduced. Finally, the application of transmission electron microscopy tomography (TEMT) on the study of order-order transition (OOT) of self-assembled block copolymer will be briefly discussed.

2. Characterization of novel amphiphilic macromolecules for drug delivery（魏广敏博士）

       内容摘要：Amphiphilic macromolecules can self-assemble into core-shell micelles in water where the hydrophobic block forms inner core and the hydrophilic block forms outer shell.  The hydrophobic inner core serves as cargo space for hydrophobic drugs.  The drug loading efficiency and delivery behavior highly depends on polymer chain structure and self-assembled hierarchical structures.  Herein, we systematically characterize two kinds of amphiphilic macromolecules, ABA triblock copolymer and nanogel star polymer, in a large length scale and time scale by light scattering and neutron scattering.  Briefly, we quantify the critical micelle concentration in dilute solution, pathway of gelation in semi-dilute solution, and temperature-induced gel-sol transition in concentrated solution.  Besides, the drug spatial distribution in hydrophobic core is characterized and the polymer chemical structure effect is evaluated.

3. Development of solid-state NMR methodology and its application in materials（张荣纯博士）

       内容摘要：Magic-angle spinning (MAS) solid-state NMR is a powerful tool for providing atomic-level insights into the structure and dynamics of various molecular systems, due to its capability of selectively manipulating different anisotropic spin interactions in solids. In particular, solid-state NMR could offer information of the structure with a length scale from 0.1nm to 100nm, and dynamics with a time scale from 1ns to 100s. Herein, I would firstly present some solid-state NMR methodologies I developed under high magnetic field (beyond 400MHz) and ultrafast MAS in the last few years, using 1H as the probe to study the microstructure and dynamics of various kinds of materials. Secondly, I would like to introduce some typical examples of solid-state NMR applications in polymer, focusing on the identification of chemical structures of unknown polymers, detection of domain structure and the corresponding dynamics in multi-component polymer systems and methodologies of in-situ detecting dynamic bonds in dynamic covalent polymers. Overall, the appropriate choice of solid-state NMR methods would enable us to extract detailed structural and dynamics information in various non-soluble and non-crystallizable systems where the solution NMR and X-ray crystallography fail, and thus will greatly benefit understanding the structure-property relationship of materials at a molecular level.
