The at least one organic acid linker has an ability to be protonated or deprotonated in response to a second pH, and the mixture of the metal solution and the linker solution has a third pH value, where the third pH value is greater than a highest pKa of the organic acid linker. The MOFs may be applied to a textile.

The side surface of the central portion of each rod may comprise planes of the form {1 0 −1 0}, {0 1 −1 0}, {−1 1 0 0}, {−1 0 1 0}, {0 −1 1 0} and {1 −1 0 0}, with central edge regions including a crystallographic plane of the form {2 −1 −1 0} or {−2 1 1 0}. The tip of the rod may comprise planes of the form {1 0 −1 1} {0 1 −1 1}, {−1 1 0 1}, {−1 0 1 1}, {0 −1 1 1} and {1 −1 0 1} with tip edge regions including a crystallographic plane of the form {2 −1 −1 2} or {−2 1 1 2}. The rods may be joined at or near their bases to form the “flower-likeâ€? morphology. In an embodiment, a synthesis mixture is prepared by dissolving a zinc salt in an alcohol solvent, followed by addition of at least two additives. The zinc salt may be zinc nitrate hexahydrate, the first additive my be benzyl alcohol and the second additive may be urea.

Particularly, the present invention is characterized by the reaction of an organo nitrile compound with a salt of mono-alkyl malonate in the presence of metal salt, and so the reaction is easy to control due to its endothermic nature, and is devoid of lachrymatory reagents with excellent reproducibility. Subsequent in situ hydrolysis in the presence of aqueous acid solution provided the compound of formula (1).
