Fritz London (1900–1954) is shown looking at clusters of various hexabenzocoronene–porphyrins in the gas phase. The clusters are held together by London dispersion interactions. Although rather small individually, they significantly add up due to the size of the molecules and the presence of tert ‐butyl groups. Interestingly, the size of the clusters—up to at least 20 molecules in one case—goes roughly along with the numbers of hexabenzocoronene units attached to the porphyrin core. This result is corroborated by X‐ray structural analyses. The illustration was made by Dominik Lungerich. More information can be found in the Full Paper by T. Drewello, N. Jux et al. on page 15818.
