| Popis | Recently acyclic oligomeric structures based on glycoluril attracted attention because of their easy modification, ability to act as host molecules, and their use for the synthesis of CB. They are usually synthesized by the controlled condensation of glycoluril units without or with substitution. The attachment of protective sidewalls yields clip-like host structures that show different recognition properties and solubilities compared to macrocyclic structures. An example for the synthesis of such a host molecule is shown Tetramer with xylylene sidewalls. X-ray diffraction showed that it forms dimeric aggregates. However, no dimerisation was observed in solution. The tetramer binds to organic cations and binding constants were determined. The binding constant were compared to a watersoluable tetramer and CB6. |
