In the article main text on page 18015, right column, the word “impossibility” in the sentence “which leads to the impossibility of obtaining a high-quality …” must be revised to “difficulty”, and on page 18019, left column, the sentence “In addition, crystallization peaks near 160 °C were also observed, which corresponded to the crystallization of copper-alkyne backbones, and corresponding crystallization enthalpies for P1, P3, P4, and P5 were 260.6, 169.0, 136.3, and 208.5 J g⁻¹, respectively.” must be revised to “In addition, the exothermic peaks near 160 °C possibly corresponded to partial destruction.”

Furthermore, in the Acknowledgements section, “the National Natural Science Foundation of China (21774120)” must be acknowledged as a funding source.
