Systems chemistry: a web themed issue

Investigating mixtures of molecules that exhibit emergent properties – this themed issue includes studies from all aspects of systems chemistry. Our guest editors, Douglas Philp, Sijbren Otto and Bartosz Grzybowski have gathered a collection of papers to demonstrate the importance of this emerging field of research.

Coupled chemical oscillators and emergent system properties

We review recent work on a variety of systems, from the nanometre to the centimetre scale, including microemulsions, microfluidic droplet arrays, gels and flow reactors, in which chemical oscillators interact to generate novel spatiotemporal patterns and/or mechanical motion.

Probing secondary interactions in biomolecular recognition by dynamic combinatorial chemistry

The implementation of dynamic combinatorial chemistry enables identification of multi-point binding ligands and receptors of biomolecules by a one-pot screening of secondary interactions.

A bistable switch in pH in urease-loaded alginate beads

A bistable switch from a low pH (unreacted “off”) state to a high pH (reacted “on”) state was obtained in enzyme-loaded gel beads in response to supra-threshold substrate concentrations.

Four acid-catalysed dehydration reactions proceed without interference

Four acid-catalysed dehydration reactions can proceed in one pot, simultaneously and without interference, to yield one imine, one acetal (or boronic ester), one ester and one alkene, even though many other cross-products could be conceived.

Interfacial mass transfer by controlled multilayer disassembly

We demonstrated the one-pot disassembly of self-propagating molecular assemblies (SPMAs) by ligand exchange and the subsequent covalent binding of the molecular components to other surfaces.

Introducing charge transfer functionality into prebiotically relevant β-sheet peptide fibrils

Amphiphilic peptide possessing non-natural aromatic groups forms fibrils consisting long range π-stacking interactions. Being similar to previously studied replicator the peptide is suggested as future component in functional self-synthesizing materials.
