Molecular daisy chains: Synthesis and aggregation studies of an amphiphilic molecular rod

摘要

A water-soluble cyclophane as the loop subunit, monofunctionalized with a molecular rod, has been synthesized to introduce a new binding motif for mechanically interlinked oligomers. It has been demonstrated that this hermaphroditic compound forms [c2]daisy chains in polar solvent over a wide range of concentrations. Furthermore, evidence for the formation of higher mechanically interlinked oligomers above the critical aggregation concentration has been obtained.
