摘要
A radical-armed guanosine derivative shows drastic magnetic changes by addition (removal) of alkali metal cations corresponding to the reversible assembly (disassembly). In the presence of templating metal ions, the assembly is formed by 8 molecules and 16 open-shell moieties confined in a sphere with a diameter of ca. 30 angstrom.
