Self‐Assembly of Water‐Soluble Glycoluril Molecular Clips Driven by Naphthalene‐Naphthalene Interaction

A water‐soluble C‐shaped receptors based on glycoluril and naphthalene building blocks is reported. The complexation formed in water was confirmed by 1 H NMR spectroscopy and NOESY technique and DOSY technique. 1 H NMR spectroscopy, fluorescence spectroscopy and DLS measurements provide strong evidence that compound 2 undergoes self‐recognition that naphthalene moiety can bind into the bisnaphthalene cleft and head‐to‐tail host–guest complexation to form new supramolecular assemblies in water. SEM and AFM visualized that the complexation formed the cyclic structure. This kind of highly designable monomer structure has great possibility to construct novel supramolecular polymer materials.
