A triphenylamine-based macromer with thiophene side groups, tris[4-(5,5’,5”-ethynyl-bithienyl)phenyl]amine (TPA-2T-Ac), was synthesized via Suzuki coupling and Sonogashira reaction. First, tris{4-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolane)phenylamine} (TPA-B) was prepared from triphenylamine (TPA) via bromination, followed by borolation reaction. Next, the TPA-B was reacted with 5-5’-dibromo-2,2’-bithiophene via Suzuki coupling reaction, resulting in tris[4-(5,5’,5”-tribromo-2-bithienyl)phenyl]amine (TPA-2T-Br). Then, this was further reacted with trimethylsilylacetylene, providing tris[4-(5,5’,5”-ethynyl-bithienyl)phenyl]amine (TPA-2T-Ac). Finally, these compounds were characterized by FT-IR, NMR and MALDI-TOF, and then optical and electrical properties were evaluated by UV/Vis and PL. In addition, the TPA-2T-Ac was subjected to thermal curing and then property evaluation by DSC, TGA, UV/VIS, PL and CV. |
