19. 3 complex between a trifurcated trisbipyridinium salt guest and a tritopic tris(crown ether) host was recently reported: J.D. Badjic, S.J. Cantrill, and J.F. Stoddart J. Am. Chem. Soc. 126 2004 2288 2289 However, this complex is still actually based on the complexation between cyclic host moieties and linear guest moieties
