Cover Picture: Bromine Bonding Induced Selective Recognition of Different Guests for Hexaphenylbenzene Bromides in the Solid State (Chin. J. Chem. 9/2015)
The cover picture shows the recognition of CH2Cl2 molecules for hexaphenylbenzene bromide HBH in solid state (Atom colors: C, gray; Br, red; Cl, green; H, white). With propeller-like shape, hexaphenylbenzene bromides display different recognition abilities for guest molecules in solid state. HBH can encapsulate CH2Cl2 or Et2O 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 MBH. In these supramolecular assemblies, bromine bonding plays an important role. More details are discussed in the article by Zhang et al. on page 1031–1036.
