The present invention relates to compounds of general formula (I),
wherein
- X is selected from a group consisting of H; C1 to C6 alkyl; halogen (F, Cl, Br or I); Y is selected from a group consisting of nitrogen; N-oxide; Z1, Z2, Zm, wherein m is 1 or 2, are independently selected from the group consisting of -CH2-CH2- and -CH2-CH2-CH2-; A, Am, wherein m is 1 or 2, are independently selected from H; -CH2COOH; -CH2C(O)NH2; -CH2P(O)(OH)2, and
- n is 1 or 2;
R1, R2, R3 are independently H; C1 to C6 alkyl; C1 to C6 alkyloxy; C6 to C10 aryloxy; benzyloxy; C1 to C6 alkylthio; C6 to C10 arylthio; F; Cl; Br; I; OH; SH; NH2; C1 to C6 alkylamino; di(C1 to C6 alkyl)amino; C1 to C6 acylamino; di(C1 to C6 acyl)amino; C6 to C10 arylamino; di(C6 to C10 aryl)amino; CN; OH; nitro; COORn, C(O)NHRn, C(O)N(Rn)2, wherein Rn is independently H or C1 to C10 alkyl or C6 to C10 aryl;
and/or neighboring two of R1, R2, R3 together with neighboring two carbon atoms of the aromatic cycle form a six-membered ring, optionally substituted with one or more substituents independently selected from the group consisting of OH, SH, CF3, F, Cl, Br, I, C1 to C6 alkyl, C1 to C6 alkyloxy, C1 to C6 alkylthio, NH2, C1 to C6 alkylamino, di(C1 to C6 alkyl)amino, NO2, COOH, COORn, C(O)NHRn, C(O)N(Rn)2, wherein Rn is independently H or C1 to C10 alkyl or C6 to C10 aryl;
with the proviso that when n is 2 and all of Z1, Z2, Zm are -CH2-CH2-, then A is not -CH2COOH;
for chromatographic separation of rare earth elements and/or s-, p- and d-block metals, as well as to the method of the separation of rare earth elements.
