Abstract

Abstract A series of N, N, N, N′-tetraaryl (Ar 1 2 Ar 2 2)-1, 1′-biphenyl-4, 4′-diamine were synthesized by the Pd (0) catalyzed CN bond formation methodology. The physical properties, including glass transit ion temperature (Tg), melting point (Mp) and oxidation potential were measured. For Ar 1= 2-naphthyl and Ar 2= 3-toly (4f) and Ar 2= 3-ethylphenyl (4h), the DSC charts indicate that they have Tg, but no observable Mp. These two ...
