Unexpected Efficiency of a Luminescent Samarium(III) Complex for Combined Visible and Near-Infrared Biphotonic Microscopy

 

The unique luminescent properties of lanthanides derivatives such as the element characteristic sharp transitions or the long lifetime are very attractive for bioimaging applications. These properties enable time-gate imaging or multiplexing imaging by mixing at least two different complexes. In the context of optical microscopy, the key parameter to maximize is the brightness.

 

An original samarium(III) complex based on a triazacyclononane platform functionalized with a charge-transfer antenna chromophore exhibited optimized brightness and was successfully used as an emissive species for two-photon microscopy experiments in both the visible and
