widely applied in liquid crystals, nonlinear optics, separation of isomers, catalysis, and
anion binding. Researches also have been conducted on the fabrication of pillar[5]
arene-based supramolecular polymers [17]. Huang and coworkers firstly introduced
halogen bond into pillar[5]arene-based supramolecular polymer [17a]. A pillar[5]
arene derivative bearing two pyridyl groups as the halogen bond acceptor was
synthesized, which could form a linear supramolecular polymer backbone with 1,4diiodotetrafluorobenzene (DITFB) in chloroform as well as in solid state (Fig. 7). With
the supramolecular polymer backbone in hand, a linear side-chain supramolecular
