Here we achieve light two different that govern monomer assembly into supramolecular fibers, as well fiber disassembly. Activation proceeds via photoredox catalysis under visible light, whereas is achieved by organometallic relies on a photocaged pre-fuel activated ultraviolet light.

However, one feature that remains thus far beyond chemists' grasp is unique ability to adapt productivity metabolic processes response triggers indicate temporary need specific metabolites. To demonstrate remarkable potential such stimuli-responsive systems, we present a metabolism-inspired network multicatalytic capable selectively synthesising range products from simple starting materials. Specifically, built four classes distinct catalytic reactions-cross-couplings, substitutions, additions, reductions, involving three materials-terminal alkyne, aryl iodide, hydrosilane.

Abstract Understanding the emergence of complex properties in dissipative non‐equilibrium systems is crucial for unraveling mysteries life processes. The review focuses on documented research chemically fueled autonomous systems, self‐sorting towards compartmentalization, self‐replication via autocatalysis, and rhythmic chemical oscillators. In addition to that, also discusses newly introduced reactions dynamic combinatorial libraries systems.
