Abstract |
Cucurbit[n]urils(CB[n]) are promising supramolecular hosts composed of glycoluril repeat units bridged by methylene group. Compared with other similar molecules, CB[n]s have unique properties that have rigid, highly symmetric and macrocyclic pumpkin-shaped structures. Its hollow cyclic structure can allow itself to contain other target molecules inside their hydrophobic cavities. Also, it can form strong host-guest interactions with identical carbonyl portals leading to generate uniform, stable sub-nanometer gaps of 0.9nm between gold nanoparticles that makes the powerful hot-spots capable of applications such as Surface-Enhanced Raman Scattering (SERS). In this study, we tried to make stable aggregations with gold nanoparticles using CB[n] as bridge molecules for regular alignments and confirm their structures and properties with analytical instruments such as electron microscopy, UV-vis, Raman spectroscopy.
