Pillared metal organic frameworks for the luminescence sensing of small molecules and metal ions in aqueous solutions

Abstract

Two pillared-layer MOFs as luminescent probes with multifunctional sensitivities to detect metal ions and small molecules were reported. Our results show that the luminescence intensities of 1a and 2a are highly sensitive to Fe³⁺ and Cd²⁺ ions and small molecules such as acetone and nitrobenzene.
