2,4,6-Trimethyl-N,N-bis(4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl)aniline (CAS 1282616-14-1) is a triphenylamine derivative carrying two pinacol boronic ester groups. It serves as a building block for preparing hole transport small molecules and polymers used in organic light-emitting devices (OLEDs), organic photovoltaics and perovskite solar cells.
One of its three aryl rings is a trimethylphenyl group, which adds a little extra steric bulk and helps the resulting molecules dissolve more readily in organic solvents. With a boronic ester at each end, the intermediate can be extended into larger structures or polymers through C-C bond-forming chemistry such as Suzuki cross coupling.
The compound can be made by reacting bis(pinacolato)diboron with N,N-Bis(4-bromophenyl)-2,4,6-trimethylaniline. It is supplied at >98% purity (1H NMR) as a white to light yellow powder or crystals, in 1 g, 2 g, 5 g and 10 g packs.
