FIELD: chemistry.
SUBSTANCE: described are styryl dyes with an ammonium group in the N-substitute of the heterocyclic residue with general formula I: 
, in which A+ represents a heterocyclic residue of formula 
or 
.
In formula I B is an aryl residue of formula IV. Also described is a method of producing formula I compounds, which involves quaternisation of hetaryl phenylethylene of formula V on the nitrogen atom of the heterocycle by reacting with an amine derivative of formula FR5.
EFFECT: compounds have considerable photosensitivity in pseudodimer complexes with crown-containing hetaryl phenylethylenes and crown-containing styryl dyes and can be used in systems for recording and storing information.
