Synthesis, functionalisation and post-synthetic modification of bismuth metal-organic frameworks

Abstract

Two new bismuth metal-organic frameworks (Bi-MOFs) have been discovered using high throughput experiments employing bismuth(III) nitrate pentahydrate and triazine-2,4,6-triyl-trisbenzoic acid (H3TATB). Long reaction times (5 d) in a water/DMF-mixture resulted in the formation of [Bi2(O)(OH)(TATB)]∙H2O (denoted as CAU-35). By switching to short reaction times and a methanol/DMF-mixture as the solvent, an analogue of CAU-7-BTB with the composition [Bi(TATB)]∙DMF∙6H2O (denoted as CAU-7-TATB) was obtained. The use of the amino-functionalised H3TATB linker (H3TATB-NH2) resulted in the formation of a functionalised porous Bi-MOF with the composition [Bi(TATB-NH2)]∙5H2O∙0.5DMF (CAU-7-TATB-NH2). The structure of CAU-35 and CAU-7-TATB were successfully solved and refined from PXRD data. CAU-7-TATB-NH2 was post-synthetically modified using anhydrides (acetic anhydride, valeric anhydride), cyclic anhydrides (succinic anhydride, phthalic anhydride) and 1,3-propane sultone. The degree of conversion ranges from 33 % to 79 %.
