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

The study of structure–activity relationships is a top priority in the development nontraditional luminescent materials. In this work, nonconjugated polyurethanes (PUs) with full-color emission (red, green, and blue) are easily obtained by control diol monomer structure polymerization conditions. Selected monomers introduced single, double, or triple bond repeating units into main chain PUs, order to understand how unsaturated bonds H-bonds affect their luminescence from molecular orbital viewpoint. Detailed experimental theoretical results show that PUs have different temperature-dependent behaviors related interplay H-bonding, through-space n−π interactions, aggregation properties. potential applications colorful displays, covert information transmission, multifunctional bioimaging been verified. This work provides new general protocol for simple preparation nonconventional fluorescent polymers deepens understanding mechanisms.
