主客体化学是指通过氢键、离子键、货车范德华力和疏水相互作用等多重非共价键合，使两个或多个分子形成复合物的化学[1-14]。基于非共价相互作用的多样性和主体分子的空间调控，所产生的复合物通常形成特定的三维结构。此外，主体-客体络合引发主体分子的电子状态和/或三维结构的显著变化，从而提供响应能力。此外，非共价键合赋予所形成的复合物可逆性和移动性。基于这些特征，具有专门设计的主体部分的分子表现出无法通过共价键合的分子系统实现的超越功能。因此，带有特殊设计的主体部分的聚合物可以通过与某些客体分子的特定主体-客体络合而成为功能聚合物。因此，聚合物的主-客体络合作用可以被看作是聚合物的非共价修饰。本章提供了一个广泛的概述功能聚合物使用主-客体化学，在这一领域的新概念，特别是详细描述。由于本书主要讨论“功能性”聚合物，因此本章不包括使用主客体化学的聚合物合成，包括超分子聚合物，这些聚合物已经在优秀的评论中总结[15-19]。此外，本章只关注主客体络合，因此简单的酸碱相互作用，金属配体配位和生物相互作用没有描述。从科学研究的角度来看，这里介绍的聚合物将吸引大量的注意力。此外，这类聚合物作为先进材料，包括智能和智能材料，具有巨大的应用潜力，从而有助于实用材料的发展。本章的研究领域涉及多个主题，因此每个部分都有一个简短的介绍。
Host–guestchemistry is defined as a chemistry that deals with the complex formation of two or more molecules through multiple noncovalent bonding such as hydrogen bonds, ionic bonds, van der Waals forces, and hydrophobic interactions [1–14]. On the basis of the multiplicity of the noncovalent interaction and spatial regulation of the host molecule, the resulting complex often forms a specific three-dimensional structure. In addition, the host–guest complexation triggers dramatic changes in the electronic states and/or the three-dimensional structure of the host molecule, thus providing a responsive ability. Furthermore, the noncovalent bonding imparts reversibility and mobility to the formed complex. On the basis of these characteristic features, molecules with specifically designed host moieties exhibit transcendent functions that are not realized by covalently bonded molecular systems. Therefore, polymers bearing specially designed host moieties can become functional polymers through a specific host–guest complexation with certain guest molecules. Thus, the host–guest complexation of the polymer could be regarded as a noncovalent modification of the polymers.This chapter provides a broad overview of functional polymers using host–guest chemistry, where new concept in this area is particularly described in detail. Because ‘‘functional’’polymers are mainly dealt in this book, polymer syntheses using host–guest chemistry including supramolecular polymers are excluded from this chapter, which have already been summarized in excellent reviews [15–19]. In addition, this chapter focuses only on host–guest complexation, and thus simple acid–base interaction, metal–ligand coordinations, and biological interactions are not described. The polymers introduced here will attract a great deal of attention from the viewpoint of scientific research. In addition, such polymers have tremendous potentials for applications as advanced materials including smart and intelligent materials, thus contributing to practical materials development. The research area in this chapter involves various topics and therefore a brief introduction is included in each section.
