Abstract

Abstract : An Yb(iii ) complex based on a dimethyl cyclen macrocyclic ligand is used as two-photon NIR bioprobe. Abstract : An Yb(iii ) complex based on a dimethyl cyclen macrocyclic ligand functionalized by charge transfer antennae was prepared. This cationic [YbL 3 ] + complex is stable and soluble in water and presents interesting photophysical nonlinear properties. It is spontaneously internalized and accumulates in live cells. High quality images have been obtained both in a classical NIR-to-vis configuration and in the more challenging NIR-to-NIR one.
