Oxidation of acyclic Schiff-base dipyrromethanes cleanly results in dipyrrins, whereas the macrocyclic ‘Pacman’ analogues either decompose or form new dinuclear copper(ii) complexes that are inert to ligand oxidation.

A copper triflate-mediated approach to access copper complexes of pyrrole-substituted corroles from the reaction of 1,9-diformyldipyrromethanes and an excess amount of pyrrole is presented for the first time. This procedure is a simple and efficient way for the preparation of corroles with a polymerizable substituent on meso-positions.
Crownphyrins, hybrid systems forged from porphyrin and crown ether counterparts, were synthesized. The novel family of macrocycles serves as dynamic, conformationallyflexible systems, able to undergo guest-induced, reversible expansion. The tunable character of their cavities allows for binding neutral and ionic guests.
