A new p-type polymer was synthesized by the oxidation coupling reaction. The monomers were prepared with highly overall yields and the obtained polymer is confirmed by elemental analysis, 1H NMR, 13C NMR, FT-IR, UV absorption, PL, and CV. The polymer is having alkyl-substituted thiophene and we are expected to have a high solubility by introducing the long alkyl-chain. Furthermore, the introduction of the alkyl chain can increase the degree of orderness by self-assembly. The thermal property of polymer was confirmed by using TGA and DSC. The polymer was showed 5% weight losing temperature at 438 oC and the curve of alkyl chain was showed around 80 ℃. The solubility of the polymer was showed a poor solubility in common solvents, such as chloroform, tetrahydrofuran, toluene. On the other hand, the polymer was showed a good solubility in chlorobenzene at room temperature with 0.7 wt%. |
