title: Mono- and terfluorene oligomers as versatile sensitizers for the luminescent Eu3+ cation.
abstract: We present the design, synthesis, and physical and photophysical characterization of Eu(3+) and Gd(3+) complexes formed with two ligands bearing either one or three fluorene sensitizer units. As a novel sensitizing approach, the oligomer length is used to control the energies of the triplet states of the sensitizer and to mediate the sensitizer to lanthanide energy transfer.
