Detection of isomeric microscopic host-guest complexes. a time-evolving cucurbit[7]uril complex

Abstract

The formation of inclusion complexes between the cucurbit[7]uril host and a cationic guest containing ferrocenylmethyl and adamantyl residues connected to an ammonium nitrogen initially leads to an ∼1:1 mixture of two isomeric microscopic complexes, which evolves as a function of time toward the thermodynamically stable mixture, dominated by the adamantyl-included complex. © 2013 American Chemical Society.
