Tribo‐Excited Chemical Reaction Using an EuIII Complex with a Stacked Anthracene Framework

Invited for the cover of this issue are Yuichi Kitagawa, Yasuchika Hasegawa, and co‐workers at Hokkaido University. The image depicts tribo‐excited chemical reaction using trivalent lanthanide complexes with stacked anthracene ligands. Read the full text of the article at 10.1002/chem.202104401. “We demonstrate a tribo‐excited chemical reaction using trivalent europium (EuIII) and gadolinium (GdIII) complexes with stacked anthracene ligands for the development of tribo‐excitation chemistry. The tribo‐oxidation and ‐dimerization reactions in the stacked anthracene ligands occur in the EuIII and GdIII complexes, respectively.” This and more about the story behind the front cover can be found in the article at 10.1002/chem.202104401).
