Preparation and nonlinear optics of monodisperse oligo(1,4-phenyleneethynylene)s

Oligo(1,4-phenyleneethynylene)s 1a-e, with solubilizing propoxy side chains, were prepared by use of Hagihara-Sonogashira coupling reactions. The synthetic strategy was based on a building block system and on the use of trimethylsilyl and triisopropylsily
