Functional supramolecular systems and materials

combining covalent and non-covalent chemistry

Abstract

The intriguing prospects of nanotechnology, sustainability, biomaterials, and the aim to close the gap between synthetic and biological molecular systems are important ingredients to study the cooperative action of molecules in the assembly towards functional supramolecular materials and systems. For chemists, the non-covalent synthesis of these supramolecular architectures is regarded as one of the most challenging objectives in science: How far can we push chemical self-assembly, and can we get control over the properties and functions of the responsive and adaptive architectures made? Moreover, the increasing number of different components in the assembly processes increases the complexity of the system, as many competing events occur, and pathway selection is needed to arrive at the state required for the function. Mastering this complexity with a combination of experiments and simulations is a prerequisite to achieve the challenges set in creating functional materials and systems. In the lecture we illustrate our approach using several examples out of our own laboratories. In all cases the control over the position of the molecules in time and space is needed. We will show the concept for their use as supramolecular polymeric materials, novel nanomaterials for spin-controlled water-splitting and as active ingredients in biomedical applications using multivalency and dilution-induced assembly processes in water.
