Control of framework interpenetration for in situ modified hydroxyl functionalised IRMOFs.
نویسندگان
چکیده
By intimate control of reaction conditions, phase-pure crystalline porous metal-organic framework materials [Zn(4)O(L)(3)] with interpenetrated and non-interpenetrated structures can be synthesised. Under certain conditions, these reactions occur with concomitant deprotection of masked alcohols located on the organic links which yield accessible 'metal-binding' functional groups within the frameworks.

Molecular simulation of hydrogen diffusion in interpenetrated metal-organic frameworks.
In this work a combined molecular dynamics simulation and dynamically corrected transition-state theory (dcTST) study was performed to investigate the effect of interpenetration (catenation) on hydrogen diffusion in metal-organic frameworks (MOFs) as well as their relationships. The results on 10 isoreticular MOFs (IRMOFs) with and without interpenetration show that catenation can reduce hydrog...
متن کاملSynthesis of functionalised nucleosides for incorporation into nucleic acid-based serine protease mimics.
The synthesis of nucleosides modified with an extra imidazole, carboxyl and hydroxyl group is described. These nucleosides can be incorporated into an oligonucleotide duplex, thus generating a novel type of serine protease mimic.
متن کاملAn Investigation on In-situ Strength and Bonding Strength of Polymer Modified Concretes (PMC) as Repair Overlays on Conventional Concrete Substrate
Polymer modified concrete (PMC) consists of Portland cement concrete with a polymer modifier. Its advantages are proper bonding strength to substrate concrete, high tensile and flexural strength and low amount of shrinkage and permeability. Using PMC overlays can be considered as a method for preservation of damaged concrete structures due to their suitable performance and durability. In this r...
متن کاملReversible interpenetration in a metal-organic framework triggered by ligand removal and addition.
Interpenetration is known for the structures of many minerals and ice; most notably for ice, it exists in doubly interpenetrating (VI, VII, and VIII) and non-interpenetrating (Ih) forms with the latter being porous and having nearly half of the density of the former. In synthetic materials, specifically in metal–organic frameworks (MOFs), interpenetration is generally considered undesirable bec...
متن کاملRhodium(II)-catalysed tandem aziridination and ring-opening: stereoselective synthesis of functionalised tetrahydrofurans.
Aziridines formed upon treatment of allylic carbamates and homoallylic sulfamates with Rh(II) carboxylate catalysts under oxidative conditions are trapped by suitably-disposed hydroxyl groups to give functionalised tetrahydrofurans.
