In this NJC paper, Marina Lezhnina et al (Muenster University of Applied Sciences-Chemical Engineering, Germany) report the synthesis and photophysical properties of Eu complexes attached to epoxy-functionalized phenantroline ligands.
The authors show how these complexes can be conveniently attached to thiol groups, in the present example gluthathione, and still retain the characteristic red emission of Eu centers.
