Abstract

Abstract : MIL-142(Sc) is prepared and the limits of the isoreticular substitution of each linker type are explored and characterised by single-crystal XRD. Abstract : Interpenetrated multicomponent MIL-142(Sc) MOFs were synthesised using the planar tritopic (4, 4′, 4′′-(1, 3, 5-triazine-2, 4, 6-triyl)tribenzoate, TATB, or 4, 4′, 4′′-(pyridine-2, 4, 6-triyl)tribenzoate, PTB) and linear ditopic (1, 4-benzenedicarboxylate, BDC, or 2-amino or 2-nitro-1, 4-benzenedicarboxylate (NH2 - or NO2 -BDC) linkers. Structure solution of the MIL-142(Sc)-TATB series from single crystal X-ray diffraction in space group R 3̄ m reveals regioselective ordering of bulky NO2 groups in MIL-142(Sc)-TATB-NO2 . Use of 1, 3, 5-benzenetribenzoate (BTB) favours instead the mesoporous Sc-BTB, the PTB analogue of which forms in the absence of BDC. The materials are highly porous: MIL-142(Sc)-TATB-BDC has a pore volume of 0.70 cm 3 g −1 .
