Synthesis and Characterization of a Novel Polymer Based on Benzodithiophene Moiety for Organic Photovoltaic Cells |
| 초록 |
BDT-NN and BDTS-NN were prepared by Stille cross-coupling polymerization. The obtained polymers have very good Solubility in organic solvents such as tetrahydrofuran, toluene, chloroform, chlorobenzene. BDT-NN Mn is 42000, Mw 104000 and PDI is 2.47. BDTS-NN Mn 33500, Mw 70800, PDI is 2.10. The photophysical properties for the polymer was investigated by UV absorption. UV absorption peaks was found at 440nm for BDT-NN and 446nm for BDTS-NN in solution and also found at 446nm for BDT-NN, 455nm for BDTS-NN in the film state. Thermal properties of BDT-NN was investigated 5 w% loss at 338oC and 384oC for BDTS-NN, it weren’t appeared glass transition temperature. HOMO energy level of BDT-NN is 5.44 eV LUMO is 3.67eV. Bandgap is 2.35. In case of BDTS-NN HOMO is 5.56eV and LUMO is 3.73. Bandgap is 2.27 for BDTS-NN. |
