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 : Rl=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. 7 cl, 3 tbl, 7 ex
