Adsorptive Separation of Methylfuran and Dimethylfuran by a Robust Porous Organic Cage.

ABSTRACT: As vital raw materials in the chemical industry, 2-methylfuran (MeF) and 2,5-dimethylfuran (DMeF) are commonly produced as mixtures. The selective separation of MeF and DMeF is crucial yet challenging, with significant industrial and economic implications. This study presents an energy-efficient separation technique using a robust calix[4]resorcinarene-based supramolecular porous organic cage (POC), CPOC-301, to effectively capture DMeF from an equimolar MeF/DMeF mixture within 2 h, yielding 95.3% purity. The exceptional separation efficiency stems from the superior structural stability of CPOC-301, maintaining its initial porous crystalline structure during separation. Calculations show that CPOC-301 forms more C-H···π
