摘要: A novel optical sensing methodology for nitrate ions has been developed using an ensemble of a synthetic receptor and colorimetric dyes as indicators. Neutral 1 forms one to complexes with anionic such Resorufin or Methyl Red in organic solvents. The equilibrium between dye is perturbed by added ion, resulting receptor–nitrate complex. displacement the indicator causes large absorbance changes, because alternation microenvironment chromophore. association constants various anions were determined analyzing intensity changes.
