Complex reaction networks govern all processes of Life. Chemistry as a discipline is moving from a focus on molecules to a focus on collections of molecules and the emergence of molecular complexity. This means that we need to understand how to study and control complex systems, how to create function… Can we interface molecular systems with electronic systems? With living systems?

Keywords: Systems chemistry, new computational and analytical tools, introduce big data/AI into organic synthesis and the study of complex systems, neuromorphic computing, interface with biology, supramolecular chemistry

The transition to a sustainable society represents an enormeous challenge. The climate change dictates that we need to rapidly reduce the use of fossile fuels, the chemical industry needs to transition to biobased feedstock and the increasing contamination of plastic in the envrionment shows that we need to rethink our use and (re-use) of these type of materials. At the same time, the access to materials to achieve this, such as those based on rare metals, is limited. These challenges set the stage for academic research in the development of novel chemical processes that are selective, waste free, and of energy friendly. New direction in this area will be at the core of this part of the IUPAC conference.
