Objectives

In biochemical systems, combinations of specialized molecular entities are precisely arranged in space to give highly complex architectures. Sophisticated functionality, such as the selective chemical transformation of substrates inside enzymes, emerges from the interplay of the individual components that are often grouped around a nanoscopic cavity. Furthermore, control mechanisms based on the cooperative binding of signal substances may regulate the enzyme’s action.

Since the advent of supramolecular chemistry, scientists construct artificial systems with ever increasing complexity and functionality that promise to serve as the basis for future developments in bottom-up nanotechnology with applications in medicine (e.g. targeted drug delivery), smart diagnostics, catalysis, material science, molecular photonics, electronics and data processing.

Metal-mediated self-assembly is a mature technique to construct such discrete, nanosized objects. So far, however, the implementation of one type of organic ligand at a time is dominating the reported, highly symmetric structures, while the tailored integration of a set of different ligands requires sophisticated approaches to avoid narcissistic separation or formation of statistical libraries. 

Nature demonstrates that the key to the most sophisticated systems lies in multi-functionalized structures. To achieve this level of complexity with artificial systems, we develop multiple strategies for the synthesis of heteroleptic coordination architectures. As a result, different functional elements can be precisely arranged inside or outside the cavity and their interplay will be studied. Combined with our recent achievements in host-guest switching, we aim at adjustable receptors, controllable molecular reaction chambers and multifunctional photo/redox systems.

    Wie macht sich die Natur Übergangsmetall-Kationen zu Nutze? Welche Relevanz haben Selten Erdmetalle wie Europium und Gadolinium in biologischen Markierungsexperimenten und der medizinischen Bildgebung? Welche spannende Chemie kann in künstlichen Nanokäfigen auf Basis von Galliumkomplexen durchgeführt werden?

    Hierzu konnte US Chemiker Ken Raymond in den letzten zwei Wochen als erster “Mercator Fellow” des GRK2376, in welchem sich Wissenschaftler von Ruhr-Uni Bochum und TU Dortmund mit chemischen Reaktionen in nanometergroßen Hohlräumen und Kompartimenten beschäftigen, spannende Antworten liefern.   Mehr hier.
