Article Synopsis
  • Copper(II)-nitroxide molecular magnets can switch spin states like spin-crossover, but understanding their properties remains difficult, especially for light-induced changes.
  • This study investigates the photoswitching and relaxation of Cu(hfac)L complexes with pyridine-based ligands using electron paramagnetic resonance (EPR) methods.
  • Results show long-lasting photoinduced spin states at low temperatures, but the effectiveness of switching is influenced by the size of the radical ligands, providing insights into the underlying mechanisms for these molecular magnets.

Precision measurements by the Alpha Magnetic Spectrometer (AMS) on the International Space Station of the deuteron (D) flux are presented. The measurements are based on 21×10^{6} D nuclei in the rigidity range from 1.9 to 21 GV collected from May 2011 to April 2021.

Metal-organic frameworks (MOFs) draw increasing attention as nanoenvironments for chemical reactions, especially in the field of catalysis. Knowing the specifics of MOF cavities is decisive in many of these cases; yet, obtaining them remains very challenging. We report the first direct assessment of the apparent polarity and solvent organization inside MOF cavities using a dedicated structurally flexible spin probe.
