A multifunctional Zr(iv)-based metal–organic framework for highly efficient elimination of Cr(vi) from the aqueous phase

An ultra-stable, multifunctional Zr-MOF material with the AIE effect has been successfully prepared, which can highly capture, selectively detect and photo-reduce Cr₂O₇²⁻ in aqueous. It can be a promising candidate for efficiently eliminating Cr(vi).
