HBH can encapsulate CH2Cl2 or Et20 molecules selectively from different solvent systems. For DBH, the recognition pattern is dominated between themselves. In CH2Cl2/toluene/Et2O system, toluene molecule can be encapsulated selectively by MBIt. In these supramolecular assemblies, bromine bonding plays an important role.展开更多
