Molecular recognition is of paramount importance for modern chemical processes and has now been achieved for small molecules using well-established host–guest chemistry and adsorption-science principles. In contrast, technologies for recognizing polymer structure are relatively undeveloped. Conventional polymer separation methods, which are mostly limited in practice to size-exclusion chromatography and reprecipitation, find it difficult to recognize minute structural differences in polymer structures as such small structural alterations barely influence the polymer characteristics, including molecular size, polarity, and solubility. Therefore, most of the polymeric products being used today contain mixtures of polymers with different structures as it is challenging to completely control polymer structures during synthesis even with state-of-the-art substitution and polymerization techniques. In this context, development of novel techniques that can resolve the challenges of polymer recognition and separation is in great demand, as these techniques hold the promise of a new paradigm in polymer synthesis, impacting not only materials chemistry but also analytical and biological chemistry.

金属-有机框架作为聚合物吸附和分离的多功能介质

分子识别对于现代化学过程至关重要，现在已经使用成熟的主客体化学和吸附科学原理实现了小分子识别。相比之下，识别聚合物结构的技术相对不发达。传统的聚合物分离方法在实践中主要限于尺寸排阻色谱和再沉淀，发现难以识别聚合物结构中的微小结构差异，因为这种微小的结构变化几乎不影响聚合物特性，包括分子大小、极性和溶解度。所以，今天使用的大多数聚合物产品都包含不同结构的聚合物的混合物，因为即使使用最先进的取代和聚合技术，在合成过程中完全控制聚合物结构也具有挑战性。在这种情况下，迫切需要开发能够解决聚合物识别和分离挑战的新技术，因为这些技术有望成为聚合物合成的新范式，不仅影响材料化学，还影响分析和生物化学。
