چکیده انگلیسی
A quinaldine functionalized probe 1 has been designed and synthesized. It exhibited selective turn-off fluorescence response toward Cu2 + ion over most of the biologically important ions at physiological pH. The binding ratio of the probe 1 and Cu2 + ion was determined to be 1:1 through fluorescence titration, Job's plot and ESI-MS. The binding constant (K) of Cu2 + to probe 1 was found to be 2.12 Ã 104 Mâ 1. Further, the Cu2 + ensemble of probe 1 was found to respond H2PO4â and HPO42 â anions among other important biological anions via fluorescence turn-on response in buffered aqueous solution at physiological pH. Fluorescence microscopy imaging using living Hela cells showed that probe 1 could be used as an effective fluorescent probe for detecting Cu2 + cation and H2PO4â and HPO42 â anions in living cells.275
