Thermally Induced Supramolecular Polymorphism Strategy Enables Fabrication of Emissive Tunable Gold Nanoclusters Assemblies

Developing controllable multicolor emissive materials is highly desirable in the field of optical devices. However, the efficient strategies to achieve this from a single gold nanoclusters (AuNCs) are still scarce. Herein, we harness a thermally induced supramolecular polymorphism strategy to get distinct nanostructures with wide-range tunable emissions in the case of thiosalicylic acid (TSA) protected AuNCs and Zn²⁺ co-assembly system by introducing excess TSA molecules.
