es with different azacrownether moieties were designed and tested as potential luminescent sensors for metal ions. The derivative containing a 1-aza-15-crown-5 as a metal chelating group was found to yield the strongest response for Ca2+ and Pb2+, exhibiting an eight- and nine-fold emission increase, respectively, while other cations induced no changes in the opticalproperties of the chemosensor

Preparative method of benzoaza-12-crown-4 preparation via condensation of o-aminophenol with trietylene glycol dichloride using sodium hydroxide as the template agent has been studied at elevated temperature in 2-propanol and n-butanol. Kinetics of the reaction mixture composition change in the course of the process has been investigated by GLC. Performing the reaction in 2-propanol leads to a higher yield of benzoaza-12-crown-4.
