Herein, we introduce a new series of highly stable MOFs, constructed using Fe3+ and Al3+ metal ions and bisphosphinate linkers. The isoreticular design leads to ICR-2, ICR-4, ICR-6, and ICR-7 MOFs with a honeycomb arrangement of linear pores, surface areas up to 1360 m2 g-1, and high solvothermal stability. In most cases, their sorption capacity is retained even after 24 h reflux in water. The choice of the linkers allows fine tuning of the pore sizes and the chemical nature of the pores. This feature can be utilized for optimization of host-guest interactions between molecules and pore walls. Water pollution by various endocrine disrupting chemicals has been considered as a global threat to public health. In this work, we proved that the chemical stability and the hydrophobic nature of the synthesized series of MOFs result in remarkable sorption properties of these materials for neurodisruptor bisphenol A.
