Abstract

Six new Cd-containing homochiral metal–organic framework materials [{Cd(L1)(Cl)}(H2O)]∞ (1a), [Cd(L1)(Br)]∞ (1b), [Cd(L2)(Cl)](H2O)]∞ (2a), [{Cd2(L2)2(Br)2}(H2O)3]∞ (2b) [{Cd(L3)(Cl)}(H2O)2]∞ (3a), and [{Cd(L3)(Br)}(H2O)2]∞ (3b) [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(CH3COO)2.2H2O and characterized via single crystal XRD, Powder XRD, variable temperature PXRD, TGA and water adsorption experiments. Side chains in different amino acid derivatives and anions (Clˉ, Brˉ) have been explored to play an important role in structural diversity (from porous to non-porous) as well as physical properties. These MOFs exhibit distinct water adsorption nature and capacity e.g. high adsorption at low partial pressure based on architectural diversities.
