Abstract
Twelve new proton-ionizable, picrylamino-type chromogenic lariat ethers der ived from dibenzo-14-crown-4, dibenzo-16-crown-5 and dibenzo-19-crown-6 dem onstrate good selectivity and remarkable color response upon extraction of alkali metal cations from basic aqueous solutions into chloroform.
