摘要：

A monosubstituted ionic polyacetylene with bulky counter anions was prepared via the ion-exchange reaction of precursor polymer by using sodium tetraphenylborate. The chemical structure of the resultiing polymer was characterized by such instrumental methods as IR, NMR, and UV-visible spectroscopies to have the conjugated backbone system with the designed functional groups. The absorption spectrum starts around 770nm, which is due to the pi -> pi* interband transition of conjugated polymer system. The photoluminescence maximum peak of polymer was located at 576nm, which corresponds to the photon energy of 2.16eV. This polymer exhibited the irreversible electrochemical behaviors between the doping and undoping peaks.
