FIELD: chemistry.
SUBSTANCE: invention relates to novel compounds in a series of indoline spirobenzopyrans (SP), specifically to ester derivatives 5’-hydroxymethyl-6-nitro-1’,3’,3’-trimethylspiro[2H-1-benzopyran-2,2’-indoline] of general formula
where R = HS- (CH2)n-; where n = 1 (SP 1), n = 2 (SP 2), n = 10 (SP 3); HOOC(CH2)2SS(CH2)2-(SP 4);
which can be used as photoactive complexing agents with quantum dots and metal cations.
EFFECT: invention can be used in nanophotonics for creating molecular switches, sensor devices, for detecting ions and for expanding the component base of molecular electronics devices.
