Front Cover: Sustainability and Chaos in the Abiotic Polymerization of 3′,5′ Cyclic Guanosine Monophosphate: The Role of Aggregation (ChemSystemsChem 1/2021)

The Front Cover illustrates that interaction between the highly ordered crystalline and disordered hydrated domains of lyophilized H‐form 3’,5’ guanosine monophosphate samples gives rise to a very complex systems chemistry. When studying the heat‐induced polymerization of this compound on longer time scales, the yield of oligomer formation oscillates, suggesting that material transport may decisively control this plausible prebiotic reaction.
