| Abstract: | A benzo-15-crown-5 modified 5-(4-carboxyphenyl)-10,15,20-triphenylporphyrin(1) was synthesized and used for binding with Hg2+ ion to form crown ether metal-prophyrin complex(3). UV-Vis and 1H NMR were used to investigate the formation and self-assembly of complex 3. The difference of 1H NMR spectra of complexes 3 and 2 reveals that a synergy effect of prophyrin and crown ether exists. The anion recognition and mechanism of complex 3 were also studied. After addition of NaNH2, an obvious red shift in the UV-Vis spectra was observed accompanied with a color change from green to chartreuse viewed by naked eye. At the same time, the chemical shift of —CH2— in crown ether ring shifted from 3.12 to 3.16 and 3.32 to 3.34, respectively. This phenomenon can be explained by the strong nucleophilic property of amino anion. However, addition of other sodium salts such as NaCl, NaH2PO4 and NaHCO3 could not result in the same phenomenon. This study provides a method for visible anion recognition. |
