Abstract

The delayed lanthanide luminescence of the terbium [Tb(III)] diaryl-urea complex 1·Tb is significantly enhanced upon sensing of dihydrogenphosphate (H2PO4) in CH3CN, which occurs through multiple anion binding through hydrogen bonding interactions and potential metal ion coordination to Tb(III).
