Synthesis and Characterization of a Novel Linear Conjugated Polymer, Poly(2,5didodecyloxy-1,4- phenyleneoctatetraynylene)

A novel linear conjugated polymer, poly(2,5-didodecyloxyphenyleneoctatetraynylene), was synthesized by an oxidative coupling of 2,5-didodecyloxy-l,4-dibutadiynylbenzene in presence of a CuCl-TMEDA catalyst under 02 . The polymer was stable under air and soluble in organic solvents. The structural analyses and the characterizations were carried out by Raman, NMR, and UV-Vis.
