| Abstract |
In this study, we synthesized two polymers with low band gap and wide absorption range up to the near infrared region for use as a donor to absorb light in polymer solar cell.
The new conjugated polymers Poly(2-heptadecyl-4-vinylthieno[3,4-d][1,3]selenazole) (PHVTS) and Poly(4-(4,8-bis(5-(2-ethylhexyl)thiophen-2-yl)benzo[1,2-b:4,5-b']dithiophen-2-yl)-2-heptadecylthieno[3,4-d][1,3]selenazole) (PBDTHTS), including selenazoles, were successfully polymerized by the stille’s reaction.
These polymers are soluble in common organic solvents such as Tetrahydrofuran, Chloroform, Toluene and etc. The molecular weight of these polymers were measured by GPC. The new polymer was characterized by 1H-NMR, 13C-NMR, FT-IR. The optical properties of these copolymers were examined by Uv-vis spectrometer. The thermal properties of these copolymers were determined by TGA. |
