Improving the Cd2+ detection capability of a new anionic rare earth metal–organic framework based on a [RE6(μ3-OH)8]10+ secondary building unit: an ion-exchange approach towards more efficient sensors

A new family of microporous anionic rare earth (RE) MOFs based on a hexanuclear (RE)₆ secondary building unit along with a post-synthetic ion-exchange method to enhance the metal ion sensing capability of anionic MOFs are reported.
