Resorcinarenes were functionalized with fluorophores and fluorescence resonance energy transfer (FRET) was employed as a tool to probe the dynamic behavior of hydrogen-bonded hexameric assemblies at nanomolar concentrations. The encapsulation of a fluorescent guest inside the capsule made it possible to observe FRET across the mechanical boundary of the hexameric assembly.
Barrett et al. (Wed,) studied this question.
