Abstract

An efficient method for the preparation of poly(p-phenyleneethynylene)s (PPEs) from direct coupling reactions between aryl diiodides and the inexpensive chemical feedstock calcium carbide is developed. A variety of PPEs can be prepared in high yields (71–93%) with the degree of polymerization between 36 and 128, offering fluorescence quantum efficiencies in the range of 0.34–0.71.
