Abstract
Recent experiments have shown that monobasic chromophoric crown ethers have very selective extraction behavior making them useful as analytical organic reagents.(1–6) The chromogenic crown ethers are synthesized by reacting a chromophore like picryl chloride to an aminobenzo crown ether. One such compound 2″4″-dinitro-6-trifluoromethylphenyl-4′-aminobenzo-15-crown-5 (1) exhibits linear response to K+ from 700-5ppm in the presence of 3000ppm Na+.Keywords
