Show more >The regulation of the concentration of a wide range of small molecules is ubiquitous in biological systems because it enables them to adapt to the continuous changes in the environmental conditions. Herein, we report an aqueous synthetic system that provides an orchestrated, temperature and pH controlled regulation of the complexation between the cyclobis(paraquat‐p‐phenylene) host (BBox) and a 1,5‐dialkyloxynaphthalene (DNP) guest attached to a well‐defined dual responsive copolymer composed of N‐isopropylacrylamide as thermoresponsive monomer and acrylic acid as pH‐responsive monomer. Controlled, partial release of the BBox, enabling control over its concentration, is based on the tunable partial collapse of the copolymer. This colored supramolecular assembly is one of the first synthetic systems providing control over the concentration of a small molecule, providing great potential as both T and pH chromic materials and as a basis to develop more complex systems with molecular communication.Show less >
