Novel Anthracene-Based Cylindrical Macrotricyclic Polyether: Powerful Host for Bispyridinium Dications

A novel anthracene-based cylindrical macrotricyclic polyether containing two dibenzo-30-crown-10 cavities has been synthesized and shown to be a powerful host to form 1:1 stable complexes with the rodlike bispyridinium dications (K(a) > 10(5) M(-1)). Moreover, it was found that the complexes could all self-assemble into linear supramolecular arrays and further 2D mosaic-like architectures in the solid state.
