Lanthanide-induced helical arrays of [{Co(<scp>iii</scp>) sepulchrate} ∩ {p-sulfonatocalix[4]arene}] supermolecules

Abstract

In the presence of lanthanide ions, a Co(III) sepulchrate cation [Co(diHOsar)]3+ and sodium p-sulfonatocalix[4]arene form a 1:1 host-guest complex which is self-assembled into a zeolite-like lattice network comprised of parallel, single stranded helices.
