Abstract:
A metal-organic framework (MOF) based luminescent probe was strategically designed for selective recognition of bisulfite anion (HS03) in water medium. The chemically stable MOF, NH2-MIL-68(In) was decorated with specific recognition site via post synthetic modification. The post synthetically modified MOF showed a selective turn on response towards bisulfite anion retaining its structural integrity. This selective recognition is also persistent even in presence of competing anions.
