FIELD: chemistry.
SUBSTANCE: invention relates to a new type of compounds - symmetrical crown-containing dienones of general formula I 
, where n=1, 2; m=0, 1, and a method for production thereof, which includes reacting cycloalkanones of general formula II 
, where n=1, 2, with formyl derivatives of benzo-crown-ethers of general formula III 
, where m=0, 1, and the process is carried out in a mixture of an organic solvent and water or in a medium of an organic solvent.
EFFECT: compounds of formula I and materials based thereon can be used in optical chemical sensors for colorimetric and luminescent determination of alkali, alkali-earth metal and ammonium cations, for example for determining trace elements of said ions in biological liquids, in industrial plants and effluents, for environmental monitoring.
