Patterns emerge everywhere and scientists have been studying them to better understand nature. Among such studies, chemists are particularly interested in spatiotemporal patterns that are formed and changed by chemical reactions. However, in ensembles of synthetic chemical systems, the patterns resulting from the diffusion of chemicals are not predictably controlled so far. To address this issue, we used audible sound as a guiding stimulus to control the dissolution, diffusion and transport of chemicals in out-of-equilibrium chemical reaction system and obtained predictable spatiotemporal patterns. Our strategy segregates a solution into spatiotemporal domains, differing in their redox or pH properties without the use of any compartmentalization-aiding motif. In addition to the colored patterns, it further helps us in organizing supramolecular aggregates along these redox- or pH-specific domains in a solution. In this talk, I will present recent findings on the sound-controlled pattern formation and their applications.
