With their electron-rich cavities and various structures, biphen[n]arenes and their
derivatives can easily bind a variety of suitable electron-accepting molecules in
organic media. As shown in Scheme 10, the guests include organic cationic molecules, neutral π-electron deficient molecules, and biological and pharmaceutical
molecules. In this section, the host–guest properties and self-assembly behaviors
of biphen[n]arenes and their derivatives towards different guests are comprehensively investigated and summarized (Table 1).
