Abstract
Comprehensive SummaryHyperbranched polysiloxanes have attracted increasing interest due to their unique fluorescence properties. However, the relatively short emission wavelength and low fluorescence lifetime are still the main obstacles to their broader application. In this study, we first synthesized a β‐diketone contained hyperbranched polysiloxane with excitation‐dependent multicolor emission. Further through the coordination of HBPSi‐NMDEA with Eu3+ ion, a hybrid luminescent material was prepared. It exhibited not only aggregation‐induced red emission at 613 nm, but also a long fluorescence lifetime of 681.45 μs. Particularly, it showed highly sensitive reversible fluorescence response to temperature variation, thus displaying the potential to be used in fluorescence temperature detection.
