  Abstract: The need for efficient and photostable   lanthanide luminescent materials is dramatically increasing, in   particular with respect to their growing application in lighting   devices and biosciences. To this end, we have developed a facile   synthesis of benzimidazole-substituted pyridine-2-carboxylic   acids that efficiently sensitize europium luminescence in   homoleptic neutral nine-coordinate complexes with overall quantum   yields of 56-61% and lifetimes of 2.1-2.6 ms in the solid state   at ambient conditions. The complexes reported here are potential   synthons for the design of a variety of luminescent materials
