Novel 2D isomorphic lanthanide complexes based on a bifunctional 5-(pyridin-3-yloxy)isophthalic acid: synthesis, structure, fluorescence and magnetic properties

The Tb( iii )-complex can be used as a multifunctional luminescent sensor presenting visual quenching responses towards acetone, Fe 3+ and CrO 4 2− in aqueous solution with high sensitivity and low detection limits.
