Synthesis of low-band gap polymers based on 3,4-dialkoxythiophene, 2,1,3-benzothiadiazole, 9,9,-dialkylfluorene, and 9,10-dialkoxyphenanthrene for organic photovoltaic device. |
| 초록 |
π-Conjugated polymer with low band gap is crucial factor for organic photovoltaics (OPVs). One of the strategies to make low band gap donor polymers is the synthesis of copolymer from electron-rich and electron-deficient units in their backbone. To obtain conjugated polymer with low band gap, we introduce electron donor-electron accepter-electron donor type monomers (dialkoxythiophene-benzothiadizole-dialkoxythiophene, TBT). 2,1,3-Benzothiadizole (BT) is well known electron deficient and 3,4-dialkoxythiophene is electron-rich compound. 9,10-Dialkoxyphenanthrene (DROPh) has planar geometry. The morphology is also very crucial factor for improving performances of OPVs. Therefore, the morphology and performances of OPV based on the copolymers with DROPh would be improved. In this presentation, we will report synthesis, photophysical, electrochemical, and photovoltaic properties. |
