Multifunctional cobalt metal–organic framework luminescent probe for the efficient sensing of Cr2O72−, MnO4− and nucleobases

A multi-responsive 3D Co-based luminescent MOF probe for the ultra-low detection of oxo-anions (Cr 2 O 7 2− , MnO 4 − ) and DNA and RNA nucleobases (adenine, cytosine, guanine, thymine, uracil) in aqueous media with good recyclability is reported.
