We show that metal-organic frameworks (MOFs) can incorporate a large number of different functionalities on linking groups in way mixes the linker, rather than forming separate domains. made complex MOFs from 1,4-benzenedicarboxylate (denoted by "A" this work) and its derivatives -NH2, -Br, -(Cl)2, -NO2, -(CH3)2, -C4H4, -(OC3H5)2, -(OC7H7)2 "B" to "I," respectively) synthesize 18 multivariate (MTV) MOF-5 type structures contain up eight distinct one phase. The backbone (zinc oxide phenylene units) these is ordered, but distribution functional disordered. arrangements several within pores lead properties are not simply linear sums those pure components. For example, member series, MTV-MOF-5-EHI, exhibits 400% better selectivity for carbon dioxide over monoxide compared with best same-link counterparts.
