文摘

Coordination-driven self-assembly utilizing labile capping ligands has been exploited as a novel strategy for metallo-cage containers. Herein, we report a tetrameric porphyrin barrel complex [C₆₀Zn₈1₄(H₂O)₄(OTs)₁₂](OTs)₄ (2) (OTs = p-CH₃C₆H₄SO₃) formed from a tetrakis(bipyridyl)porphyrin ligand 1, Zn(OTs)₂, and a template guest, C₆₀ fullerene. The tetrameric-barrel 2 contains two kinds of bis(bpy) Zn^II centers coordinated by TsO^{鈥?/sup> anions which serve as labile capping ligands in the formation of the finite structure of 2.}
