The extremely rare examples of dynamic single crystals where excitation by light or heat induces macroscopic motility present not only a visually appealing demonstration of the utility of molecular materials for conversion of energy to work, but they also provide a unique opportunity to explore the mechanistic link between collective molecular processes and their consequences at a macroscopic level...
Das Aufplatzen der Einkristalle dreier ZnII‐Komplexe unter UV‐Licht wird von P. Naumov, J. J. Vittal et al. in ihrer Zuschrift auf S. 6017 ff. beschrieben. Dieses visuell eindrucksvolle dynamische Verhalten resultiert aus der Akkumulation und plötzlichen Freisetzung von mechanischer Spannung infolge von [2+2]‐Photocycloadditionen im Kristall. Ein Verständnis dieses Effekts, der an das Aufplatzen von...
