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.

1176合作研究中心的目标是建立聚合物材料的合成与迄今为止无与伦比的三维结构控制程度。在这样做的过程中，目标分子精度可以实现定量结构-性质关系研究，定义功能或获得新型材料，最终导致广泛的新应用。通过维度组织原理对软材料分子结构的关注有助于对合成挑战进行分类，并将科学发现从一个维度转移到另一个维度。高分子材料的性能主要由其分子结构及其空间排列和连接决定。这种分子结构可以是小结构单元沿着链的序列（一维）、链长系综的均匀性或大分子内的支化度。官能团沿着链的精确放置可以确定和调节链在溶液中的行为-所谓的卷曲行为。表面（二维）可以由重复单元组成，或者用大分子装饰，这赋予表面特定的功能。在网络（三维）中，所得到的材料的复杂性质由单个网格的长度或功能性构建块的顺序决定。CRC 1176中这些高精度大分子的合成得到了表面分析平台、新型表征方法以及分子动力学和量子力学计算的补充。
