4-SUBSTITUTED N-ARYL-1,8-NAPHTHALIMIDES, EXHIBITING PROPERTIES OF FLUORESCENT SENSORS ON METAL CATIONS AND METHODS FOR PRODUCTION THEREOF Russian patent published in 2014 - IPC C07D411/10 C07D413/10 C07D273/08 C09K11/06 

FIELD: chemistry.

SUBSTANCE: invention relates to novel 4-substituted-N-phenyl-1,8-naphthalimides which contain in the N-aryl nucleus a crown ether residue (with a different combination of oxygen, nitrogen and sulphur atoms) of general formula (I) , where R¹=NO₂, Br, NH₂, OCH₃, NHCOCH₃, Ia: R^l=NO₂, X=S, n=1; Ib: R¹=NO₂, x=NCH₃, n=1; Ic: R¹=NO₂, X=NCH₃, n=2; Id: R¹=Br, X=NCH₃, n=2; Ie: R¹=NH₂, X=S, n=1; If: R¹=NHCOCH₃, X=S, n=1; Ig: R¹=OMe, X=S, n=1; Ih: R¹=OMe, X=NCH₃, n=1; Ii: R¹=OMe, X=NCH₃, n=2, where compounds If-Ii exhibit properties of fluorescent sensors on cations of alkali-earth, transition and heavy metals, and compounds Ia-Ie are intermediate compounds in the process of synthesis of compounds If-Ii. The invention also relates to a method of producing a compound of formula (I) and intermediate compounds of formula (II)

EFFECT: obtaining novel sensors on cations of alkali-earth, transition and heavy metals, novel methods of producing compounds of the given formula.
