Halogen-substitued effect of side chain end of the conjugated polymer Via optoelctronic devices |
| 초록 |
The development of a light-harvesting system that can be improved the power conversion efficiency is important. In OPV, the introduction of modification of the side chain molecular design can interesting part of the organic solar cells. In particular, the Fluorine atoms are known to enhance intermolecular C-F…H, F…S and C-F…π interaction. Though these interesting properties, only a few researches are investigated to introduce them at the end of the side chain. In this presentation, we investigated the effect of fluorine atoms at the end of the side chain in conjugated polymers. these polymer was synthesized by stille-polymerization. These synthesized molecules molecular weight was measured by GPC analysis. Optical and electrical properties measured by UV-Vis absorption spectroscopy, Cyclic voltammetry. Finally, organic solar cells and organic photodiodes were fabricated using novel molecules and their performance was investigated. |
