Abstract Monodisperse asymmetrical oligo(phenylene‐ethynylene)s were synthesized iteratively by combining the selective deprotection and the Sonogashira coupling. Trimethylsilylethyl ester (TSE) and trimethylsilyl (TMS) were used as protecting groups for carboxyl and acetylene, respectively. The acetylenic TMS protecting group could be removed selectively by the treatment with TBAF in methylene chloride
