Three new boronic acid derivatized lanthanide-polyoxometalates (BA-Ln-POMs) were synthesized, in which boronic acids served as bi- or tri-dentate ligands and exhibited interesting coordination ability towards POMs and LnIII. The pH was found to be crucial in controlling the coordination modes of boronic acid and the formation of B-O-Ln and B-O-Nb bridges. Compared with the boronic acid-free Ln-POM, a longer lifetime was observed for compound 2Eu due to the coordination of boronic acids to the EuIII center.
