A reaction-triggered luminescent Ce4+/Tb3+ MOF probe for the detection of SO2 and its derivatives†
Abstract
A reaction-responsive Ce4+/Tb3+ MOF luminescent probe/test strip was designed and synthesized for sensing gaseous sulfur dioxide and sulfite in human serum. A novel sensing principle based on the chemical reaction of Ce4+ with analytes to powerfully sensitize the luminescence of Tb3+ ion has been proposed.
