By increasing the number of pyrrole groups in a porphyrin ring from the usual four to 12, an international team of chemists has succeeded in making the largest aromatic molecule known to date (Chem. Eur. J. 2015, DOI: 10.1002/chem.201500650). Expanding the realm of aromaticity is nothing new for Dongho Kim of South Korea’s Yonsei University and Atsuhiro Osuka of Japan’s Kyoto University. Their groups have been collaborating . . .
