A dehydrobenzo[12]annulene attached by three platinum catecholate units is oxidized chemically or electrochemically to generate mono‐, di‐, and trications. Similarly, a platinum catecholate complex with a dibenzo[8]annulene framework also generates mono‐ and dications upon oxidation. On the basis of theoretical and spectroscopic studies with respect to energetic, structural, and magnetic criteria, these dications are deduced to be aromatic, thus demonstrating a new method for stabilizing aromatic dications.
