SFB 1176:  Molekulare Strukturierung weicher Materie

• Subject Area: Chemistry ; Physics
• Term: from 2016 to 2020
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 259079535

The Collaborative Research Centre 1176 aims to establish the synthesis of polymeric materials with a so far unmatched degree of structural control in three dimensions. In doing so, the targeted molecular precision enables quantitative structure-property relationship investigations, a defined function, or access to a novel class of materials, eventually resulting in a wide range of novel applications The focus on the molecular structure of soft materials by a dimensional organising principle facilitates to classify the synthetic challenges as well as to transfer the scientific findings from one dimension to another. The properties of macromolecular materials are primarily determined by their molecular structure and its spatial arrangement and linkage. This molecular structure can be the sequence of small building blocks along the chain (one-dimensional), the uniformity of the chain-length ensemble or the degree of branching within the macromolecule. The precise placement of functionalities along the chain can determine and regulate the behaviour of the chain in solution - the so-called coiling behaviour. Surfaces (two-dimensional) can consist of repeating units or be decorated with macromolecules, which impart specific function to the surface. In a network (three-dimensional), the complex properties of the resulting material are determined by the length of the single mesh or by the sequence of the building blocks of functionalities. The synthesis of these high-precision macromolecules within CRC 1176 is complemented by a surface analysis platform, novel characterisation methods as well as molecular dynamic and quantum mechanical calculations.
