| 제목 | A study on the fluorescence property of the perylene derivatives with methoxy groups |
| 초록 | Perylene dyes with methoxy groups in the terminal-, bay-, or both positions were synthesized to understand the effect of the methoxy groups on the fluorescence quenching. The methoxy groups were sequentially placed at the ortho-, meta-, or para-position of each substituent. Additionally, perylene-based dyes with ethyl groups in place of the methoxy groups were designed and synthesized to serve as control, these dyes have similar geometrical molecular structures and conjugation systems with the dyes containing methoxy groups. The methoxy groups of terminal-substituents had a lesser effect on fluorescence quenching than the methoxy groups of bay-substituents. Moreover, only the methoxy groups at the para-position of the bay-substituents strongly affected on fluorescence quenching. These results showed that the fluorescence of the dyes are influenced by the electron donating effect of the methoxy groups when the methoxy groups are involved in the main conjugation systems of the dyes. |
