Fluorecent property investigation of novel crown ether derivatives |
| 초록 |
Novel type of crown ether derivatives of tris-crown ether were synthesized from diformyl-dibenzo-24-crown-8 with 4-aminobenzo-15-crown-5 by the linkage of Schiff base. Diformyl-dibenzo-24-crown-8 was prepared from 3,4-dihydroxybenzaldehyde reacted with tri-ethyleneglycol ditosylate. The complexation behavior and fluorescent properties of the newly synthesized tris-crown ether were examined. When complex with Li+ , Na+, K+, Rb+ and Cs+ cations, the absorbance increased. The complexation does not affect the shape of the fluorescence excitation and emission spectra, but the fluorescence intensity at 398 nm enhanced. |
