Porphyrin-cyclophanes: Inclusion complexation and x-ray crystal structure of a zinc octamethyldiphenylporphyrin
摘要:
The synthesis, characterization, and complexation properties of two novel porphyrincyclophanes are reported. In the first system, one face of an octamethyldiphenylporphyrin is capped by one diphenylmethane unit. In the second system, both faces of a tetraphenylporphyrin are strapped by diphenylmethane units. The X-ray crystal structure has been determined for the singly-capped zinc octamethyldiphenylporphyrin.

derivatives by cyclophanes. The major attractive host-guest interactions in these complexes are π-π stacking and edge-to-face aromatic-aromatic interactions. Individual studies investigate relative binding strength as a function of (i) the electronic properties of the guests, (ii) the nature of the solvent, and (iii) the nature of the cyclophanehosts. For these investigations, two new tetraoxa [n.l
