Overview
Related Products

2,5-Bis(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)terephthalaldehyde (CAS number 2305615-53-4), is a benzene derivative with two aldehyde and two pinacolborane substituents. Both the aldehyde groups and pinacolborane groups are located at the para-positions. 2,5-Bis(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)terephthalaldehyde serves as a versatile ligand and it is readily employed as a monomer for Suzuki cross-coupling reactions and amination reactions. Notably, the functional groups do not interfere with each other during these reactions. It makes the COFs synthesised from 2,5-bis(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)terephthalaldehyde ideal for post-functionalization after the polymer network is formed.

2,5-Bis(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)terephthalaldehyde is also used in the synthesis of poly(phenylenevinylene) for 2D semiconducting materials, through aldol condensation.
