Abstract
Poly(phenylacetylene)[Poly(PA)] was prepared by the polymerization of phenylacetylene with the catalyst of (NBD)PdCl2. The instrumental analysis data on the polymer structure revealed that the poly(PA) have the conjugated polyene backbone structure with phenyl substituents. The band gap energy of poly(PA) was estimated to be 2.51 eV and the photoluminescence spectra of poly(PA) showed that the photoluminescence peak is located at 439 nm, corresponding to a photon energy of 2.82 eV. The cyclovoltamograms of poly(PA) exhibited that the irreversible oxidation and reduction were occurred at 0.38 V and −0.93 V, respectively (vs Ag/AgNO3). The redox current value gradually increased as the scan rate increased.
