Two metal–organic frameworks, {(NH2Me2)[Zn(Pycia)]}n (MOF-1) and {(NH2Me2)[Zn2(Pycia)(PBA)]}n (MOF-2), have been synthesized based on pyrazole functionalized carboxylic acid ligands for organic dye adsorption. The enlarged pore dimension of MOF-2 suggests the advantage of additional linear auxiliary ligand for the structure tuning of the MOFs. Furthermore, the anionic frameworks of the MOFs endow them with size selective adsorption toward different cationic organic dyes.
