ORGN 431 |
| Two novel anion fluorescent probes 1a and 1b were designed and synthesized. In the structures, two 1,8-naphthalimide fluorophores were connected with phthalic acid and isophthalic acid through ethylenediamine, here ethylenediamine was used as recognition acceptor and four hydrogens on imino group were intended to act with anion through hydrogen bond, to study the effect on selectivity and sensitivity of anion recognition caused by different distance between the two ethylenediamine recognition acceptors. Their absorption and emission spectra were detected in DMSO at room temperature. The recognition ability to different anions such as HSO4-, CH3COO-, H2PO4-, F- and NO3- etc. was also studied. |
