New class of metalloproteins tailored for upconversion luminescence
Upconversion, the process by which two photons are converted into a single one having higher energy, has been observed in few materials, most notably those doped with lanthanide ions. Funded by the Marie Skłodowska-Curie Actions programme, the UCLnProt project plans to design the first of their kind metalloproteins for upconversion. To this end, researchers will combine lanthanide complexes, which demonstrate excellent photophysical properties, with coiled coil scaffolds. These proteins, which are coiled together like the strands of a rope, can selectively bind to different lanthanide ions at defined locations and distances. Project work should help generate a new class of ligands, adding it to the toolbox of lanthanide coordination chemistry.
