A novel, simple but efficient diamine (TriPEDA) containing rigid nonplanar conjugated triphenylethylene moieties was designed and synthesized through Wittig–Horner and Suzuki coupling reactions. Four kinds of high-performance functional polyimides were thus prepared by the dipolymerization of TriPEDA and four dianhydrides, respectively.
