In the growing field of single-mol. mechanochromism, the potential of transition metal complexes is yet to be examined The authors synthesized [Cu(phen)2]+ complexes: bis-Cu(I)-phenanthroline, bis-Cu(I)-phenanthroline-2-amine, and bis-Cu(I)-phenanthroline-2-acetamide. After that, the authors characterized the complexes by UV-visible spectroscopy and employed d. functional theory (DFT) calculations to study the changes in UV-visible upon mech. pulling via force calculations The results of the authors′ examination of time-dependent (TD)-DFT-calculated UV-visible suggests that the bis-Cu(I)-phenanthroline-2-acetamide complex is predicted to have an observable shift of the metal-to-ligand charge transfer band upon pulling from 0 to 0.6 nN in the visible region. The authors demonstrated the ability to synthesize and characterize bis-Cu(I)-phenanthroline-2-acetamide. The TD-DFT calculations predict an observable shift in the visible region of the UV-visible spectrum. Transition metal complexes are feasible candidates as mechanophores and are worthy of further exploration as to their potential role in a new subclass of mechanochromic indicators.
