文摘

CB[n] (n = 6–8) is a family of synthetic macrocyclic host molecules composed of n glycoluril units, which can be employed as molecular reactor. N-Phenyloxypropyl-N′-ethyl-4,4′-bipyridium (1) was designed to form a host–guest inclusion complex with CB[n] (n = 6–8), subsequently, the bromination reaction of 1 and its corresponding inclusion complexes was investigated in this work. In the case of 1/CB[8], the folded including mode is quite helpful to acquire 1-bormination product completely through intramolecular charge transfer (ICT), and CB[8] can provide a safe bromination environment for 1.
