Merck, 657336-5G, 1,3,5-Tris(bromomethyl)benzene

General description
1,3,5-Tris(bromomethyl)benzene has three bromo substituents around an aromatic ring that can be used as a cross-linker. It is mainly utilized in the synthesis of ligands and dendrimeric monomers.
Application
A monomer for synthesizing dendrimers and light emitting oligomers.
1,3,5-Tris(bromomethyl)benzene can be crosslinked with triptycene monomers by using Friedel-Crafts alkylation reaction to form microporous polymers for selective adsorption of CO₂ and H₂. Proton exchange membranes (PEMs) can be fabricated by covalently linking polybenzimidazole (PBI) and 1,3,5-tris(bromomethyl)benzene as part of the tri-functional bromomethyls for fuel cell applications. It is also used in the synthesis of trifluoroacetamide derivative triaza[3₃]cyclophane.
