  Chromogenic Diaza-Crown Ether Dicarboxylic Acids for Determination of Calcium Ions

  摘要：

  The synthesis of two novel calcium chromoionophores 2 and 3, which are based on a benzodiazacrown ether with an inward-facing methoxyl group and bear two acetic acid groups and a 2,4,6-trinitroanilino chromophore, is described. Calcium and magnesium responses at pH optima are determined. Compound 2 exhibits a 31-nm bathochromic shift of the absorption maximum, an increase in the absorptivity upon complexation with Ca2+, and good selecitivity for Ca2+ over Mg2+ at pH 10.3. The response of chromoionophore 2 is linear from 0 to 8 X 10(-3) M Ca2+.
