We will synthesize molecular spoked wheels based on a phenylene backbone with various sizes and functionalities. These structures are monodisperse, highly stable, and will contain side groups at their six corners to guarantee their processability. It will be clarified if our recently reported synthesis of the purely phenylene-based molecular spoked wheels can be also transferred to the synthesis of larger structures. Depending on the synthetic results, we will prepare the first molecular spider web, characterize it thoroughly and investigate its respective supramolecular chemistry. Moreover, we will investigate the synthesis and properties of spoked wheels with a reduced symmetry that allow the attachment of two different side groups, each at three of the six corners of the wheel. In addition, hybride structures of rigid spoked wheels will be prepared in which a central rigid molecular spoked wheel is decorated with coil-like flexible oligomers of different molecular weight and different polarity. We will investigate the influence of the chemical structure and of the chain length on the supramolecular nanostructure formation and on the miscibility of the wheels with classical homo polymers.

我们将合成基于亚苯基骨架的分子辐条轮，具有各种尺寸和功能。这些结构是单分散的，高度稳定的，并且在其六个角处含有侧基以保证其可加工性。这将澄清，如果我们最近报道的纯苯为基础的分子辐条轮的合成也可以转移到更大的结构的合成。根据合成结果，我们将制备第一个分子蜘蛛网，对其进行彻底表征并研究其各自的超分子化学。此外，我们将研究辐条轮的合成和属性，减少对称性，允许两个不同的侧组，每个在三个车轮的六个角落的附件。此外，将制备刚性辐条轮的混合结构，其中中心刚性分子辐条轮用不同分子量和不同极性的线圈状柔性低聚物装饰。我们将研究化学结构和链长对超分子纳米结构形成的影响以及对具有经典均聚物的轮子的相容性的影响。
