| Zusammenfassung: | Superstructures assembled by polyoxometalate (POM) clusters have attracted considerable attention due to their intriguing architectures and remarkable properties. The development of novel inorganic-organic hybrid materials exhibiting aggregation-induced emission (AIE) characteristics represents an important research direction. However, POM-based nanostructures that integrate both POM clusters and AIE luminogens (AIEgens) have rarely been reported in the literature. Herein, we designed and synthesized two POM-based hybrid materials, denoted as TPE-POM-1 and TPE-POM-2, through electrostatic self-assembly between tetraphenylethylene (TPE)-derived cationic AIEgens (TPE-1 and TPE-2) and Keggin-type silicotungstic acid (K4[α-SiW12O40]). The self-assembled morphologies and AIE properties of TPE-POM-1 and TPE-POM-2 were systematically investigated. The two AIEgen-modified POM clusters demonstrated remarkably enhanced AIE characteristics and controllable formation of diverse nanostructures, including layered and onion-like spherical micelles, free-standing films, and vesicular architectures in various solvent systems (tetrahydrofuran (THF)-water, THF-methanol, and chloroform-methanol). The proposed approach of this study presents a crucial design strategy for achieving precise control over the coassembly of POM-based hybrid materials with AIE characteristics through noncovalent interactions |
