ABSTRACT:
A chelate formed between Eu.sup.3+, Tb.sup.3+, Dy.sup.3+ and Sm.sup.3+ and a compound having the formula ##STR1## where A.sub.1-6 are single carbon or nitrogen atoms; n=1 or 2; R.sub.1-6 is nothing when A is a nitrogen, and hydrogen or an organic group when A is a carbon; Z and Z' are selected among --N(CH.sub.2 CH.sub.2 COO.sup.-).sub.2, --N(CH.sub.2 COO.sup.-).sub.2, --N(CH.sub.2 OPO.sub.3.sup.2-).sub.2 and --N(CH.sub.2 PO.sub.3.sup.2-).sub.2 ;--species that --X--Y is a substituent replacing a hydrogen anywhere in the parent compound; and --X--Y represents an organic group containing no chelating heteroatom closer than four atoms from a chelating heteroatom in the parent compound and X is a stable bridge containing certain groups and Y is selected from (a) specified relative groups allowing coupling to other compounds and (b) residues of compounds participating in biospecific affinity reactions.
