Sonogashira coupling is another extensively utilized reaction for the construction of triplebonded
CPs from alkynes [25]. The polymerizations of terminal alkynes and aryl halides are
catalyzed by palladium and copper catalysts, generating poly(aryleneethynylene)s (PAEs).
Sonogashira polycoupling is highly efficient in terms of technical simplicity and tolerance to
numerous functional groups. For example, the silole-containing diyne 7 is reactive to both
