摘要

Heterocyclic ligands are common sensitizers for thelanthanide ions emission upon UV irradiation. Of particularinterest are Tb(III) and Eu(III) ions in combination with acyclic,macrocyclic and macropolycylic ligands incorporatingheterobiaryls, such as 2,2'-bipyridyl, 1,10-phenanthroline, 1,1'-biquinoline, 3,3'-busoquinoline, and their derivatives. Much morepowerful sensitizers are the same systems bearing N-oxidefunctions, furthermore their complexes are more stable than theparent heterocycles. Such luminescent materials are the basis fortime-resolved fluoroimmunoassays displaying very high sensitivity,and serve as materials for advanced medical diagnostics. In thisshort review, a brief presentation will focus on state-of-the-artphotochemistry and photophysics of the lanthanide complexes ofheterocyclic and N-oxide-incorporating heterocyclic systems.
