A molecular sponge that exclusively adsorbs acetonitrile†
Abstract
We report that a tetra-armed cyclen (L) with phenylethynylmethyl (Ph–CC–CH2–) groups as side-arms forms L·CH3CN (L·AN) inclusion crystals from acetonitrile–organic mixed solvents with high selectivity and acts as if it is an acetonitrile selective molecular sponge.
