Perfluorinated Aromatic Spacers for Sensitizing Europium(III) Centers in Dinuclear Oligomers : Better than the Best by Chemical Design ?

Abstract :

Transfer news : The use of a simple method allows the various sensitization steps in Eu(III) -containing complexes to be deciphered. Incorporation of an increasing number of electron-withdrawing fluorine atoms on the rigid and electronically tunable phenyl spacer between two tridentate binding units (see picture, red O, dark blue N) affects the quantum yield, intersystem crossing, and energy transfer processes in a rational way.
