Abstract

A new approach is reported for tailoring the pore geometry in five series of multivariate metal-organic frameworks (MOFs) based on the structure [Zn2(bdc)2(dabco)] (bdc = 1,4-benzenedicarboxylate, dabco = 1,8-diazabicyclooctane), DMOF-1. A doping procedure has been adopted to form series of MOFs containing varying linker ratios. The series under investigation are [Zn2(bdc)2-x(bdc-Br)x(dabco)]·nDMF (bdc-Br = 2-bromo-1,4-benzenedicarboxylate), [Zn2(bdc)2-x(bdc-I)x(dabco)]·nDMF (bdc-I = 2-iodo-1,4-benzenedicarboxylate), [Zn2(bdc)2-x(bdc-NO2)x(dabco)]·nDMF (bdc-NO2 = 2-nitro-1,4-benzenedicarboxylate), [Zn2(bdc)2-x(bdc-NH2)x(dabco)]·nDMF (bdc-NH2 = 2-amino-1,4-benzenedicarboxylate) and [Zn2(bdc-Br)2-x(bdc-I)x(dabco)]·nDMF . Series demonstrate a functionality-dependent pore geometry transition from the square, open pores of DMOF-1 to rhomboidal, narrow pores with increasing proportion of the 2-substituted bdc linker, with the rhomboidal-pore MOFs also showing a temperature-dependent phase change. In contrast, all members of series and have uniform pore geometries. In series this is a square pore topology, whilst series exhibits the rhomboidal pore form. Computational analyses reveal that the pore size and shape in systems and is altered through non-covalent interactions between the organic linkers within the framework, and that this can be controlled by the ligand functionality and ratio. This approach affords the potential to tailor pore geometry and shape within MOFs through judicious choice of ligand ratios.

Attention Score in Context

Attention Score in Context

This research output has an Altmetric Attention Score of 3. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 01 March 2016.
All research outputs
#15,287,671
of 26,150,873 outputs
Outputs from Dalton Transactions: An International Journal of Inorganic Chemistry
#5,814
of 21,401 outputs
Outputs of similar age
#200,394
of 403,129 outputs
Outputs of similar age from Dalton Transactions: An International Journal of Inorganic Chemistry
#256
of 2,102 outputs
Altmetric has tracked 26,150,873 research outputs across all sources so far. This one is in the 41st percentile – i.e., 41% of other outputs scored the same or lower than it.
So far Altmetric has tracked 21,401 research outputs from this source. They receive a mean Attention Score of 1.9. This one has gotten more attention than average, scoring higher than 72% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 403,129 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 49th percentile – i.e., 49% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 2,102 others from the same source and published within six weeks on either side of this one. This one has done well, scoring higher than 87% of its contemporaries.
