SYNTHESIS, BINDING-PROPERTIES AND SELF-FUNCTIONALIZATION OF A STEROID-CAPPED PORPHYRIN

A porphyrin capped with a steroidal superstructure bearing convergent hydroxy groups has been synthesized and shown to bind a variety of functionalized amines via a combination of metal-amine and hydrogen-bonding interactions; the metal-ligand interaction was used to catalyse and control selective acylation of a single hydroxy group in the cap.
