3,4,3-LI(1,2-HOPO): in vitro formation of highly stable lanthanide complexes translates into efficacious in vivo europium decorporation.

The spermine-based hydroxypyridonate octadentate chelator 3,4,3-LI(1,2-HOPO) was investigated for its ability to act as an antenna that sensitizes the emission of Sm(III), Eu(III), and Tb(III) in the Visible range (Φ(tot) = 0.2-7%) and the emission of Pr(III), Nd(III), Sm(III), and Yb(III) in the Near Infra-Red range, with decay times varying from 1.78 μs to 805 μs at room temperature.
