Multicolor lanthanide‐doped polymers have found versatile applications in data encryption, sensing, and smart display. However, multiple components, sophisticated design, and complex preparation procedures are often required. In contrast, their intrinsic and multicolor fluorescence emission is been effectively used. Herein, Eu‐doped polyurethane (ETP@PU), integrating tunable multicolor emission, self‐healing, and multi‐responsiveness, is prepared through a facile route via step‐growth polymerization of PU using commercial Eu‐ligand (Eu(TTA)3Phen, ETP) as a fluorophore. FTIR and XPS analysis demonstrate the successful coordination of Eu3+ with carbamate groups of PU, which not only enhances the mechanical properties of PU but also bestows unique luminescent properties. With increasing ETP content, the intrinsic fluorescence of PU declines, while that of Eu displays a discernible enhancement, resulting in the tunable multicolor emission. The highest quantum yield of Eu‐related emission reaches 71.3% due to the robust coordination and efficient energy transfer between Eu3+ and PU. Moreover, the ETP@PU exhibits excellent self‐healing capacity and multi‐responsiveness, and their potential applications are also investigated in the field of light‐emitting diodes, data encryption, and self‐healing process monitoring. This work provides a facile and efficient strategy to develop multicolor lanthanide‐doped polymers promising for various applications.

Organic luminescence materials makes the molecule more enthusiastic in wide variety of applications. The luminescent organic materials are in a attraction of the researchers, and the Aggregation‐Induced Emission (AIE) is attributed to the occurrence that particular chromophores (typically fluorophores) display very low or nearly no emission in the monomolecular soluble state but become highly emissive when forming aggregates in solution or in solid state. This phenomenon is relatively abnormal when compared with many other traditional fluorophores. AIE research suppresses aggregation‐caused quenching (ACQ). Nevertheless, the carbon dots (CDs) and quantum dots have shown to have tyical florescence properties, therefore, recent years many researchers have also attracted for their developments. The CDs, luminescent, and AIE materials are not only used in biomedical applications and organic light‐emitting diodes but also in sensing, self‐assembly, and other areas. One should introduce promising material to a designed framework that exhibits AIE characteristics to ensure moral results in AIE. Amongest, AIE‐active tetraphenylethylene (TPE) is attractive fluorophores due to its easy synthesis strategy. This review article discusses the synthesis properties of TPE, CDs, and luminescent materials with a broad range of applications. We have outlined linear, branched‐shaped supramolecular, and hybrid macromolecules due to its potential in the future.
