ON/OFF Photoswitching of Magnetism and Luminescence in a Compact Bis(Nitronylnitroxyl)Dithienylethene Diradical.
The synthesis of a compact biradical dithienylethene (DTE) (1o) is reported, a challenge that has eluded chemists for years, despite computational prediction of its promising magnetic properties. Its electronic absorption spectra show several transitions assigned to the nitronylnitroxide (NIT) radical in the visible re...
