Cucurbituril-based supramolecular host-guest complexes: single-crystal structures and dual-state fluorescence enhancement
Two supramolecular complexes were prepared using cucurbiturils [CBs] as mediators and a four-armed p -xylene derivative ( M1 ) as a guest molecule. The single crystals of these two complexes were obtained and successfully analyzed by single-crystal X-ray diffraction (SCXRD). An unexpected and intrig...

Zusammenfassung: | Two supramolecular complexes were prepared using cucurbiturils [CBs] as mediators and a four-armed
p
-xylene derivative (
M1
) as a guest molecule. The single crystals of these two complexes were obtained and successfully analyzed by single-crystal X-ray diffraction (SCXRD). An unexpected and intriguing 1 : 2 self-assembly arrangement between
M1
and CB[8] was notably uncovered, marking its first observation. These host-guest complexes exhibit distinctive photophysical properties, especially emission behaviors. Invaluable insights can be derived from these single-crystal structures. The precious single-crystal structures provide both precise structural information regarding the supramolecular complexes and a deeper understanding of the intricate mechanisms governing their photophysical properties.
