FIELD: chemistry.
SUBSTANCE: invention relates to novel compounds in the family of azole-substituted spiroheterocyclic compounds, and specifically 5'-(1,3-benzothiazol-2-yl)-substituted spiro[indoline-naphthopyrans] of general formula 
, where R1=C1-C6 alkyl, R2=H, C1-C6 alkyl, alkoxyl, halogen.
EFFECT: compounds of formula (I) exhibit photoreversible complexing agent properties and can be used, for example, as a sensitive element of photo-controlled chemical sensors of trace amounts of ions of the zinc subgroup of metals with optical response.
