Synthesis and post-synthetic modification of MIL-101(Cr)-NH2via a tandem diazotisation process

Abstract

The functionalised metal–organic framework MIL-101(Cr)-NH₂, containing 2-aminobenzene-1,4-dicarboxylate as the linker, has been synthesised. A new tandem post-synthetic modification strategy involving diazotisation as the first step has been developed and used to introduce halo- and azo dye-functional groups into the pores.
