논문초록 Highly fluorescent supramolecular nanostructures based on cucurbit[8]uril(CB[8]) complex in aqueous solution have received considerable attention because of their great potential for various applications with their unique photophysical properties and low toxicity. Herein, we designed and synthesized a bent structural organic guest molecule bearing cyanostilbene backbone. By the host-guest interaction with CB[8], the cyanostilbene derivative was self-assembled into necklace-shaped macrocyclic hexamers in the aqueous system, which was identified by Job’s plot, DLS, ESI-MS, and DOSY-NMR measurements. It should be noted that the necklace-shaped nanostructures showed considerably enhanced fluorescence emission (ΦPL = 0.68) than the non-assembled monomers (ΦPL = 0.02) in the aqueous solution.
