SUBSTANCE: present invention relates to new compounds, and more specifically to 5-formyl-substituted indoline spirobenzopyrans with general formula 1 where R1, R2 - Alk or c-Alk; R3 -CHO or NO2 group (electron-acceptor substitute), with photochromic properties. The invention also relates to the method of producing 5-formyl substituted derivatives of indoline spirobenzopyrans with formula 1. Spirobenzopyrans, which have electron-acceptor substitutes in the pyran part of the molecule, are subjected to direct selective formylation in position 5 in a trifluoroacetic acid medium with urotropine (hexamethylenetetramine) at boiling point of the mixture in an inert atmosphere for 1-1.5 hours. The obtained 5-formyl-substituted spirobenzopyrans are photochromic compounds are photochromic and can be used for making new photochromic materials (recording devices or information storage; photo-switching activity of biological objects and polymer matrices, complex formation; information security media, maps, special document protection equipment) or as advanced initial compounds for further synthesis of a large number of new photochromic objects.

EFFECT: wider field of application of the compounds.
