Abstract

A novel, photochromic N∧C-chelate organoboron functionalized dipicolinic acid (H₂L) has been designed and synthesized. Lanthanide(III) complexes based on this ligand (L) with the general formula [NBu₄]₃[LnL₃] (Ln = Eu or Tb) were prepared. The new ligand was found to be effective in both sensitizing and photomodulating the emission of a Eu(III) ion. The photoisomerization conversion of the boryl chromophore attached to the ligand of the lanthanide complex was determined to be quantitative by NMR analysis of the La(III) analogue.
