Functional Metal Organic and Covalent Organic Frameworks
The chemistry of porous frameworks has undergone a renaissance in recent years, driven by the prospect of realizing complex supramolecular architectures by directed self-assembly of tailor-made molecular building blocks. We pursue a bottom-up approach towards 2D and 3D organic and metal-organic frameworks (COFs and MOFs) as well as carbon nitrides by using dynamic covalent chemistry and fine-tuning of their properties by chemical design. Focal areas include the synthesis of highly porous and chemically robust framework architectures for thermal and photocatalysis, optoelectronics, and energy storage applications. Instrumental to our work is an in-depth understanding of the real structure of the frameworks and the nature of defects, along with the principles governing framework formation. We address these questions using local and long-range spectroscopic and diffraction techniques as well as in situ diffraction methods.
