摘要
[GRAPHICS] Novel self-assembled molecular capsules were constructed from two moles of pyridine-containing porphyrin derivatives and four moles of Pd(II) complexes utilizing a pyridine-Pd(ll) interaction. The H-1 NMR spectral studies established that these self assembled molecular capsules 5 and 6 have a highly symmetrical D-4h structure as well as a large inside cavity. It was shown that molecular capsule 6 can include a large bipyridine guest by a two point simultaneous pyridine-Zn(II) interaction.
