摘要：Supramolecular polymers are made of monomers that are held together by noncovalent interactions. This is the reason for the wide range of novel properties, such as reversibility and responses to stimuli, exhibited by supramolecular polymers. A range of supramolecular polymerization methods have been developed leading to a number of novel supramolecular materials. However, standard techniques for the characterization of supramolecular polymers have yet to be established. The dynamic nature of supramolecular polymers makes them difficult to be fully characterized using conventional polymer techniques. This tutorial review summarizes various methods for characterizing supramolecular polymers, including theoretical estimation, size exclusion chromatography, viscometry, light scattering, vapor pressure osmometry, mass spectrometry, NMR spectroscopy, scanning probe microscopy, electron microscopy, and atomic force microscopy-based single molecule force spectroscopy. Each of these methods has its own particular advantages and disadvantages. Most of the methods are used to characterize the supramolecular polymer chain itself. However, some of the methods can be used to study the self-assembled state formed by supramolecular polymers. The characterization of a supramolecular polymer cannot be realized with a single method; a convincing conclusion relies on the combination of several different techniques.

点评：
超分子聚合物是指借助分子间的非共价键自组装形成的一类动态超分子聚集体。相比于传统的高分子合成方法，自组装超分子聚合物为复杂构筑高分子的形成提供了一条便捷的途径。本综述详细介绍了研究和表征超分子聚合物的各种技术和手段，例如理论计算、体积排阻色谱（SEC）、粘度法、光散射、质谱、核磁共振、扫描探针、电子显微镜以及单分子力谱等手段和方法，对以后的超分子聚合物的研究具有指导意义。
