Two new series of metal–organic frameworks (MOFs), termed M-VNU-74-I and -II (where M = Mg, Ni, Co; VNU = Vietnam National University) were designed to expand the methanol uptake capacities with polar amide functionalities. The resulting MOFs, isoreticular to MOF-74, exhibited high porosity (up to 3000 m2 g–1) as well as the highest reported methanol uptake [>1 g g–1 or >400 cm3 cm–3]. As a representative example, Mg-VNU-74-II was shown to maintain a remarkably high stability and methanol mass transfer capacity for at least 42 ad/desorption cycles (3 days). Indeed, these findings highlight the potential of such materials for practical use in adsorption heat pump applications.

Three new lanthanide-based metal–organic frameworks (Ln-MOFs), namely MOF-590, -591, and -592 constructed from a tetratopic linker, benzoimidephenanthroline tetracarboxylic acid (H4BIPA-TC), were synthesized under solvothermal conditions and fully characterized. All of the new MOFs exhibit three-dimensional frameworks, which adopt unprecedented topologies in MOF field. Gas adsorption measurements of MOF-591 and -592 revealed good adsorption of CO2 (low pressure, at room temperature) and moderate CO2 selectivity over N2 and CH4. Consequently, breakthrough experiments illustrated the separation of CO2 from binary mixture of CO2 and N2 with the use of MOF-592. Accordingly, MOF-592 revealed the selective CO2 capture effectively without any loss in performance after three cycles. Moreover, MOF-590, -591, and -592 showed to be catalytically active in the oxidative carboxylation of styrene and CO2 for a one-pot synthesis of styrene carbonate under mild conditions (1 atm CO2, 80 °C, and without solvent). Among the new materials, MOF-590 revealed a remarkable efficiency with exceptional conversion (96%), selectivity (95%), and yield (91%).

Gas adsorption measurements of MOF-591 and -592 revealed good adsorption of CO₂ (low pressure, at room temperature) and moderate CO₂ selectivity over N₂ and CH₄. Accordingly, breakthrough measurements were performed on a representative MOF-592, in which the separation of CO₂ from binary mixture containing N₂ and CO₂ was demonstrated without any loss in performance over three consecutive cycles. Moreover, MOF-590, MOF-591, and MOF-592 exhibited catalytic activity in the one-pot synthesis of styrene carbonate from styrene and CO₂ under mild conditions (1 atm CO₂, 80 °C, and solvent-free).
