A new arylamine monomer with photo-crosslinkable styrylpyridinyl moiety of conjugated polyarylamine for OLED hole injection material was synthesized through two synthetic routes, BOC-amine protection/deprotection and nitro group reduction methods. Both synthetic routes yielded practically pure amine product by standard aqueous workup and crystallization in 61% overall yield from pyridinylvinylphenol 2. Their reaction efficiencies ...
