Description 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 1,3,5-Tris(bromomethyl)benzene can be crosslinked with triptycene monomers by using Friedel-Crafts alkylation reaction to form microporous polymers for selective absorption 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. A monomer for synthesizing dendrimers and light emitting oligomers. Packaging 5, 10 g in glass bottle
