Synthesis of photo-responsive ligands and its application to Cs+ extraction from aqueous solutions |
| 초록 |
Photo-responsive azo benzo crown ethers (a-BCEs) were prepared as Cs+ ligands. Structures of a-BCEs and their intermediates were confirmed by FTIR and NMR. UV-vis absorption studies confirmed photo-switching abilities of the compounds. One a-BCE was preliminarily tested for LLE in two modes: (1) extraction by irradiation under UV then stripping under visible light using different stripping agents and (2) vice versa. The cis-isomer performed better Cs+ uptake (~ 43 mg g-1) compared to the trans-isomer (~ 33 mg g-1). Stripping by conversion of cis to trans (> 94% desorption) performed better than trans to cis (63-93% desorption). Further studies are ongoing. This study was supported by the National Research Foundation of Korea (NRF) grant funded by the Ministry of Science and ICT (2020R1A2C1003560, 2021R1A2C2093746, and 2021R1H1A2008284), Basic Science Research Program through the Ministry of Education (2020R1A6A1A03038817). |
