FIELD: chemistry.
SUBSTANCE: invention relates to a novel type of compounds - N-alkylazacrown-containing styrene dyes of general formula I: 
in which A+ is a heterocyclic residue of formula 
or 
In formula (I) - fragment of N-alkylbenzoazacrown-ether of formula (IV): 
where R6 is a lower alkyl; n=0-3; to a method of preparing the said compounds, as well as to novel composite film materials based on formula (I) dyes.
EFFECT: efficient optical chemosensory properties with respect to cations of alkali and alkali-earth metals.
