A series of cost‐effective hyper‐cross‐linked polymers (HCLPs) are synthesized from naphthalene via the external cross‐linker (ECL) knitting method, the solvent knitting method, and the Scholl coupling reaction, respectively. According to multiple characterizations, the resulting polymers are thermally stable and fluorescent with large specific surface areas (SSAs) and narrow pore distributions. In particular the HCLP synthesized using dimethoxymethane as the ECL exhibits SSAs up to 2870 m² g⁻¹ and shows a great potential in gas adsorption applications. Naphthol and 1‐methylnaphthalene are used as monomers to synthesize HCLPs by the above three methods to investigate whether introducing functional groups to naphthalene would improve properties of the resulting polymers. Moreover, HCLPs feature high SSAs, outstanding thermal and fluorescent performances, and facile synthesis, making them promising candidates for industrial applications.

通过不同方法研究萘及其衍生物基微孔有机超交联聚合物

萘分别通过外部交联剂（ECL）编织法，溶剂编织法和Scholl偶联反应从萘合成了一系列具有成本效益的超交联聚合物（HCLP）。根据多个特征，所得聚合物是热稳定的并且具有大的比表面积（SSA）和狭窄的孔分布的荧光。特别是，使用二甲氧基甲烷作为ECL合成的HCLP表现出的SSA高达2870 m ² g ^-1并且在气体吸附应用中显示出巨大的潜力。萘酚和1-甲基萘被用作通过上述三种方法合成HCLP的单体，以研究将官能团引入萘是否会改善所得聚合物的性能。此外，HCLP具有较高的SSA，出色的热和荧光性能以及易于合成的特性，使其成为工业应用的有希望的候选者。
