The research focuses on the controlled one-pot synthesis and in situ ester hydrolysis of non-interpenetrated and interpenetrated metal-organic frameworks (MOFs), specifically [Zn4O(L1)3] and α-[Zn4O(L1)3], using biphenyl-2,2’-diol links (L1). The study investigates the impact of reaction conditions, including solvents like N,N’-diethylformamide (DEF) and dimethylformamide (DMF), on the formation of these frameworks. The researchers found that the choice of solvent significantly influences whether the resulting MOF is interpenetrated or non-interpenetrated. The frameworks were synthesized with accessible hydroxyl functional groups, which were demonstrated to be reactive by complexation with copper ions. The study also explores the effect of these functional groups on CO2 adsorption, revealing a significant increase in the enthalpy of adsorption compared to non-functionalized IRMOF-1. The research highlights the potential for controlling pore chemistry and interpenetration in MOFs through careful selection of solvents and masking groups, paving the way for the development of MOFs with tailored properties for various applications.
