Luminescence of lanthanides is attractive for biological applications due to its long lifetime and sharp emission profiles. We describe the split display of a lanthanide binding ligand that allows facile evaluation of dimerizing proteins. The split lanthanide ligand is cysteine reactive, and therefore should be readily applicable to a variety of protein systems.

Innovative Tb3+ antenna complexes employing two different substituted 2-hydroxyphthalamide ligands (HxOH-IAM and bis-HxOH-IAM) acting simultaneously as coordinating sites and light collector units have been synthesized and successively anchored in silica layers by the sol-gel technique. The complexes show remarkable photoluminescence (PL) quantum yields in methanol solution, as high as 0.30 and 0.40 for (HxOH-IAM)4?Tb 3+ and (bis-HxOH-IAM)2?Tb3+, respectively. The grafting of the Tb3+ complexes in silica single layers accomplished by exploiting the terminal hydroxyl groups of the IAM chains results in highly transparent and homogeneous films displaying bright green emission and PL efficiencies of up to 0.40. The silica layers containing the (bis-HxOH-IAM)2?Tb3+ show remarkable photostability even under prolonged and continuous irradiation (up to 3.5 h). The nature of the IAM ligands allows the photoexcitation of the complexes at wavelengths even longer than 350 nm, which is a spectral window suitable to develop luminescent lanthanide probes dedicated to bioanalyses and bioimaging applications.
