Abstract
AbstractA new Tb(III) complex based on 3‐pyridylacetic acid, [Tb(H(3‐PAA)2)(NO3)2] (1, 3‐PAA=3‐pyridylacetic acid), has been triumphantly prepared and structurally characterized. Complex 1 is a 1D chained structure linked by carboxylate groups of the 3‐PAA ligand, and its 2D supramolecular packing is controlled mainly by hydrogen‐bonds. The compound exhibits outstanding thermal stability and excellent stability under ethanol solutions. Moreover, compound 1 shows a strong solid‐state green‐emitting emission at room temperature, which demonstrates that the ligand can effectively sensitize the emission of the Tb(III) ion, and it can serve as a responsive sensing material for detecting the Fe3+ ion in ethanol solutions.
