| 英文摘要 | A nerv cyclodextrin derivative (DMAC - CD) was prepared by linking a chalcone moiety to the 6 C position of beta - cyclodextrin with an aza - oxa - alkyl chain. The interaction between DMAC - CD and transitional metal ions were studied by steady state and time - resolved fluorescence spectroscopy. The experimental results showed that the complexes of DMAC - CD with metal ions were formed in the aqueous solution due to its self - inclusion conformation, which was in favor of binding metal ions. For this reason, the quenching curve of different metal ions for DMAC - CD all deviated from the Stern - Volmer linear relationship owing to the steady state quenching mechanism. The stability constants and fluorescence quenching rate constants were both determined, indicating this chalcone - modified cyclodextrin has a higher sensitivity and selectivity for transitional metal ions, especially for Cu2+. |
