摘要：

In this study, we reported the construction of 3D supramolecular polymeric networks using per-imidazole pillar[5]arene (DIMP5) as a host and 1,4-diiodotetrafluorobenzene (L) as a halogen bond donor in chloroform. The supramolecular polymerization process was characterized by 1H NMR, 19F NMR spectroscopy, and X-ray single crystal analysis. The C & horbar;I & ctdot;N distance (2.78 & Aring;) and C & horbar;I & ctdot;N angle (177 degrees) clearly indicated the formation of halogen bonds in the crystal structure. Meanwhile, by introducing adiponitrile (G) as the guest, a supramolecular polymerization of pseudo[2]rotaxanes was also prepared, which was driven by DIMP5-based host-guest complexations and halogen bonding interactions.
