Photoswitching of an intramolecular spin exchange interaction between a copper(II) ion and a nitroxyl radical by using a metalcomplex of diarylethene has been studied by means of ESR spectroscopy. As a coordination ligand, a diarylethene with a 1,10-phenanthroline ring and nitronyl nitroxide radical was synthesized. Mixing the diarylethene ligand with [Cu(hfac)(2)] (hfac=hexafluoroacetylacetone) in
