Abstract Birefringent crystals are crucial in modulating the polarization state of light within contemporary technological applications. Organic molecules with π‐conjugated structure known to exhibit significant birefringence effect owing their unique electronic properties. This study demonstrates that 4, 5‐dichocyanimidazole can be used as a new crystal building block for birefringent crystals. Crystals C 5 N 4 H 2 ( DCI ) and ·H O DCI‐w obtained by evaporation at room temperature. It is worth noting birefringence. At 546 nm, experimental 0.417 calculated reaches 0.618. The significantly larger than those all commercial exceeds most metal‐free First‐principles calculations structural analysis show this remarkable mainly due strong anisotropy planar well‐organized arrangement groups. discovery opens up possibilities development high‐performance optical materials.

Abstract 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 halogen bond donor in chloroform. The polymerization process was characterized by 1 H NMR, 19 F NMR spectroscopy, X‐ray single crystal analysis. C─I⋯N distance (2.78 Å) angle (177°) clearly indicated formation bonds structure. Meanwhile, introducing adiponitrile G guest, pseudo[2]rotaxanes also prepared, which driven ‐based host–guest complexations bonding interactions.
