A linear multiporphyrinic
A linear multiporphyrinic [2]-rotaxane has been synthesized using the transition metal-templating method for threading a gold(III)-incorporating macrocycle onto a rodlike, phenanthroline-derived chelate bearing carboxylate end groups. Stoppering has been performed by reacting the resulting prerotaxane with the amino derivative of a zinc tetraarylporphyrin under EDC-HOBt activation. A 34% yield has been realized for this one-pot, double amide bond formation.
