Abstract
[GRAPHICS] A linear multiporphyrinic [2]-rotaxane has been synthesized using the trans ition metal-templating method for threading a gold(III)-incorporating macro cycle onto a rodlike, phenanthroline derived chelate bearing carboxylate en d groups. Stoppering has been performed by reacting the resulting prerotaxa ne with the amino derivative of a zinc tetraarylporphyrin under EDC-HOBt ac tivation. A 34% yield has been realized for this one pot, double amide bond formation.
