Abstract: We show that metal-organic frameworks (MOFs) can incorporate a large number of different functionalities on linking groups in a way that mixes the linker, rather than forming separate domains. We made complex MOFs from 1,4-benzenedicarboxylate (denoted by "A" in this work) and its derivatives -NH2, -Br, -(Cl)2, -NO2, -(CH3)2, -C4H4, -(OC3H5)2, and -(OC7H7)2 (denoted by "B" to "I," respectively) to synthesize 18 multivariate (MTV) MOF-5 type structures that contain up to eight distinct functionalities in one ph… Show more

“…For example, preliminary results show that the molecular pores can be imbibed into various porous supports, such as cellulose filter paper, to introduce a degree of microporosity into otherwise macroporous materials. Our results also suggest the possibility of modular 'mix and match' strategies in which a number of different molecular pores are combined in a single-amorphous solid, each perhaps containing a different chemical functionality 39 , without satisfying the stringent requirements of co-crystallization 40 .…”

“…The mixture was stirred at rt for 24 h. ZrCl 4 (0.2 mmol, 1 equiv), H 2 bpdc (0.167 mmol), and water (1 mmol, 5 equiv) were then added. The mixture was first stirred at room temperature for 10 min, and then heated under stirring at 100 8C in an oil bath for 72 h. After cooling, the solid was separated by centrifugation, washed sequentially with DMF (15 mL), MeOH (15 mL), water (15 mL), and acetone (15 mL), and dried at 80 8C in vacuum (0.1 mmHg) for 10 h. 6 ]DMSO and stirred at room temperature for 5 h to allow digestion of the MOFs. The solution was then transferred to an NMR tube.…”

“…In all cases (Table 1, entries 1-8), crystalline materials were obtained ( Figure 4). ICP-AES showed that the iridium contents were systematically lower at higher temperatures (Table 1, entries 1-4 vs. [5][6][7][8]. The amount of LM1 was determined by analysing the samples by 1 H NMR spectroscopy after digestion under optimized conditions (i.e., [D 6 ]DMSO/D 3 PO 4 ; see the Supporting In- [a,b] bpdc [c] bpydc [ Next, we explored the effect of stirring during the synthesis of the MOF, with the aim of decreasing demetallation of LM1 and increasing the yield.…”

“…While tailoring structure/property generally refers to design/synthesis of new ligands and frameworks, some PCP prototypes can adopt several different metal ions and/or ligands, providing a rational strategy for adjusting the structure/property, albeit only in a limited degree 5,8,[12][13][14] . A few of these prototypes can even form mixedcomponent (solid-solution) crystals with variable concentration/ ratio of functional building blocks, which in principle allows the structure/property to be adjusted more continuously and precisely 15,16 . However, so far there is no rational strategy to directly monitor/control the composition of solid-solution frameworks during the synthesis process because complicated reaction environments involving solvents and/or liquid reactants are generally required for known direct-synthesis and postsynthetic modification (PSM) 3,7,[17][18][19][20][21] methods.…”
