FIELD: chemical industry.
SUBSTANCE: invention relates to symmetric bis-N-methyl aza-crown-containing dienons of general formula I, where n= 1, 2; m=0, 1. The invention also relates to a method for obtaining a compound of formula I.
EFFECT: new compounds have been obtained that can be used as part of optical chemosensors for colorimetric and luminescent determination of cations of alkaline, alkaline earth metals and ammonium, for example, to determine the micro-quantities of these ions in biological fluids, in industrial waters and effluents, for environmental monitoring.
