Abstract Despite extensive research on enhancing the strength, toughness, or impact resistance of elastomers, materials that simultaneously integrate these properties remain elusive. In this work, a multifunctional elastomer is developed with high superior and excellent by designing multiscale structures. The synergistic coupling strong weak hydrogen bonds, rigid ring‐flexible chain coordination, precise control hard/soft block ratio enabled development an optimized architecture tailored for performance, achieving tensile strength 84 MPa toughness 450 MJ m⁻ 3 , while maintaining across varying strain rates. Additionally, incorporation hindered urea dynamic covalent bonds bond‐induced localized conjugation effect impart thermal adhesion fluorescence capabilities, broadening material's functional application scenarios. This molecular design strategy not only facilitates tailoring high‐performance but also provides new insights into structure‐property relationships in elastomers.
