Synthesis and Properties of an Aliphatic Substituted Polyacetylene: Poly(1-hexyne) |
| 초록 |
Poly(1-hexyne) was prepared by the polymerization of 1-hexyne by using transition metal catalyst. The instrumental analysis data on the polymer structure revealed that the poly(1-hexyne) have the conjugated polyene backbone structure with n-butyl substituents. Poly(1-hexyne) showed UV-visible absorption band at 276 nm and PL spectrum at 415 nm, indicating relatively blue-shifted PL maximum value. From the relationship plot of the oxidation current density (log ip,a) as a function of the scan rate (log v), it was found that the oxidation current of poly(1-hexyne) versus the scan rate is approximately linear relationship in the range of 30 mV/sec ~ 150 mV/sec and the exponent of scan rate, x value is found to be 0.424. It is explained by that the kinetics of the redox process are close to the diffusion-control process. The band gap energy of poly(1-hexyne) was estimated to be 2.98 eV and HOMO and LUMO level values of poly(1-hexyne) were 5.35 and 2.37 eV, respectively. |
