A molecular sponge that exclusively adsorbs acetonitrile

We report that a tetra-armed cyclen ( L ) with phenylethynylmethyl (Ph-C&z.tbd;C-CH 2 -) groups as side-arms forms L ·CH 3 CN ( L · AN ) inclusion crystals from acetonitrile-organic mixed solvents with high selectivity and acts as if it is an acetonitrile selective molecular sponge. A tetra-arme...
