Abstract

Abstract: A spin‐selective tribo‐chemical reaction using a dinuclear lanthanide complex is demonstrated for the first time. The dinuclear complex is composed of two Eu III ions, hexafluoroacetylacetonato ligands, and anthracene‐based phosphine oxide bridges. Single‐crystal analysis revealed a face‐to‐face‐type anthracene dimer structure in the dinuclear Eu III complex. Mechanical stimulus on the dinuclear Eu III complex induced selective formation of oxidized anthracene. The tribo‐chemical reaction is based on a characteristic energy‐transfer pathway for the selective formation of an excited triplet state.

Single‐crystal analysis revealed a face‐to‐face‐type anthracene dimer structure in the dinuclear Eu III complex.

This first spin‐selective tribo‐chemical reaction using a Eu III complex will offer new possibilities for the development of tribo‐excitation chemistry.
