2,4,6-tris-4-(BROMOPHENOXY)-1,3,5-TRIAZINE: A HEXAGONAL HOST FRAMEWORK ASSEMBLED WITH ROBUST Br...Br TRIMER SYNTHONS

摘要

Based on the trigonal symmetry of the title triazine 1 and the Br_3 supramolecular synthon, a hexagonal host system has been designed and shown to include hexachlorobenzene, 2, 4, 6-collidine, 1-methylnaphthalene and mesitylene guests in its porous structure. In the 1. hexachlorobenzene (2 : 1) inclusion clathrate 2, the guest molecule is ordered and bonded to the host through Cl...O interactions. In the channel structures 3, 4 and 5, the solvent molecules are disordered and the host-guest stoichiometry is 1 : 1. These supramolecular structures highlight the importance of weak hydrogen bonds and heteroatom interactions in the self-assembly of target networks. The generality of the new host system is also demonstrated.
