This project is concerned with the characterization of relevant structural and dynamic properties of amphiphilic conetworks synthesized through heterocomplementary linking of star macromolecules with different arrangements of the blocks with different philicity. These model networks are prepared and further characterized by other experimental and theoretical methods in the framework of the Research Unit 2811. We focus in particular on mechanical properties of and molecular transport through these networks, which are studied by rheological methods and pulsed-gradient NMR, respectively. These findings are correlated with microscopic observables of the local network structure, which is probed by specific NMR methods. Given the broad range of amphiphilic, notably selectively swollen and partially transient as well as switchable networks, we expect to elucidate the molecular and structural basis of the mechanical and transport properties.

本项目研究了不同亲和度的星形大分子通过异互补连接合成的两亲网络的相关结构和动力学性质。这些模型网络是在2811研究单元的框架内用其他实验和理论方法制备和进一步表征的。我们特别关注通过这些网络的力学性质和分子运输，分别通过流变学方法和脉冲梯度核磁共振进行研究。这些发现与局部网络结构的微观观察结果相关，并通过特定的核磁共振方法进行了探测。考虑到广泛的两亲性，特别是选择性膨胀和部分瞬态以及可切换的网络，我们希望阐明机械和运输性质的分子和结构基础。
