Supramolecular sorting machine separates aromatic and aliphatic compounds

How can aromatic compounds be separated from aliphatic compounds efficiently without having to rely on energy-intensive processes? In an article published in the journal Angewandte Chemie International Edition, chemists from Heinrich Heine University Düsseldorf (HHU) present an innovative molecular sieve made of partially fluorinated macrocycles that can separate these compounds selectively.
