title: 8,16,24,32,40,48-Hexamethoxy[2.6]metacyclophane-1,9,17,25,33,41-hexayne: a novel near-planar ammonium-selective ionophore.
abstract: The titled cyclophane (cyclic [6]metaphenylacetylene) with six methoxy groups inside the cavity has a nearly planar carbon framework, forms open-channel structures in the crystal, and exhibits an ammonium-selective ionophoric property in spite of the considerably large cavity.
