Abstract

Supramolecular arrays composed of alternating tetracyanoethylene acceptors (A) and 1,4-dioxybenzene-based donors (D) self-assemble spontaneously in the solid state. Infinite one-dimensional […A…D…A…D…] stacks are formed by co-crystallizing tetracyanoethylene and 1,4-dimethoxybenzene. When bis- p-phenylene-34-crown-10, possessing two 1,4-dioxybenzene donors (D-D) bridged by polyether chains, is employed, infinite one-dimensional […A…D-D…A…D-D…] arrays are formed with the cavities of macrocyclic polyethers of adjacent stacks perfectly in register to afford channels — occupied by MeCN molecules — along one crystallographic direction.
