Abstract

The hunt for red luminescence: The tetrahedrally shaped terpyridine-based ligand (left) forms red luminescent nanoparticles upon addition of EuIII ions (centre), which can be transformed in dual luminescent probes that feature red and near infrared emission (right) upon addition of NdIII ions.

Abstract

A tetrahedral shape-persistent molecule equipped with four terpyridine ligands can form an oligomeric structure upon complexation with metal ions, in which two terpyridine units are intermolecularly connected via a metal ion. The most interesting results were obtained upon binding of lanthanide ions, whose luminescence is sensitized by the ligand. In particular, dual luminescent probes were obtained upon concomitant complexation of two different lanthanide ions, such as EuIII and NdIII.
