A biological complex which consists of a biologically active molecule, associated by coupling or adsorption to a macropolycyclic rare earth complex, said macropolycyclic rare earth complex consisting of at least one rare earth salt complexed by a macropolycyclic compound of the general formula: (see fig.I) in which Z is a trivalent or tetravalent atom; R is nothing when Z is trivalent or represents hydrogen, a hydroxyl group, an amino group or a hydrocarbon radical when Z is tetravalent, and the divalend radicals A, B and C independently of one another are hydrocarbon chains, said hydrocarbon chains optionally contain one or more heteroatoms and said hydrocarbon chains optionally interrupted by a heteromacrocycle, at least one of the radicals A, B or C also containing a least one molecular unit or essentially consisting of a molecular unit, said molecular unit possessing a greater triplet energy than the emission level of the complexed rare earth ion. The invention also relates lo the macropolycyclic rare earth complexes as above defined as well as to a process for detection or determination of an analyte and to a process for enhancing the fluorescence of a rare earth.
