Final Report Abstract

Various methods have been developed for operating functional artificial multicomponent systems via metal ion pulses. Here, the discrete addition of a fuel acid temporarily triggered a release of metal ions followed by their retrieval, which triggered a pulse-like self-sorting of various components into a temporary functional unit. We carried out various catalytic reactions (simple, parallel, sequential, tandem reactions) via the addition of the fuel acid in a timemodulated manner as well as molecular-logic processes encoded in the frequency range.
