Six new Cd-containing homochiral metal–organic
framework
materials [{Cd(L1)(Cl)}(H<sub>2</sub>O)]<sub>∞</sub> (<b>1a</b>), [Cd(L1)(Br)]<sub>∞</sub> (<b>1b</b>), [Cd(L2)(Cl)](H<sub>2</sub>O)]<sub>∞</sub> (<b>2a</b>), [{Cd<sub>2</sub>(L2)<sub>2</sub>(Br)<sub>2</sub>}(H<sub>2</sub>O)<sub>3</sub>]<sub>∞</sub> (<b>2b</b>) [{Cd(L3)(Cl)}(H<sub>2</sub>O)<sub>2</sub>]<sub>∞</sub> (<b>3a</b>), and [{Cd(L3)(Br)}(H<sub>2</sub>O)<sub>2</sub>]<sub>∞</sub> (<b>3b</b>) [L1 =
2-((pyridin-4-yl)methylamino)-4-methylpentanoic acid], [L2 = 2-(pyridin-4-yl)methylamino)-3-hydroxypropanoic
acid], and [L3 = 2-((pyridin-4-yl)methylamino)-3-hydroxybutanoic acid]
have been synthesized using pyridine functionalized amino acid (l-leucine, l-serine, and l-threonine) homochiral
links and Cd(CH<sub>3</sub>COO)<sub>2</sub>·2H<sub>2</sub>O and
characterized via single crystal X-ray diffraction (XRD), powder X-ray
diffraction (PXRD), variable temperature powder X-ray diffraction
(VTPXRD), thermogravimetric analysis and water adsorption experiments.
Side chains in different amino acid derivatives and anions (Cl<sup>–</sup>, Br<sup>–</sup>) have been identified to play
an important role in structural diversity (from porous to nonporous)
as well as physical properties. These metal–organic frameworks
(MOFs) exhibit a distinct water adsorption nature and capacity, e.g.,
high adsorption at low partial pressure based on architectural diversities.
