摘要：

We describe the straightforward synthesis of a new polyacid ligand derived from the bis-pyrazolyipyrimidine motif that displayed excellent properties concerning its ability to sensitize the emission of lanthanides. Emission lifetimes were in the range of ms and quantum yields were 0.15 and 0.85 for Eu and Tb, respectively, among the largest measured by us in related compounds, thus making this ligand an excellent candidate for its application in multitagging time-resolved fluoroimmunoassays.
