Abstract

A membrane with an optical response to chloride has been developed that contains two luminophores that display two largely different decay times. The first luminophore (the "reference") is a chloride-insensitive ruthenium metal-ligand complex possessing a decay time in the microsecond range. The second luminophore is the short-lived chloride-quenchable fluorescent probe lucigenin. Both are ...
