Röhr, David Schmidt, Ivo Krummenacher, Holger Braunschweig, Frank WürthnerBy variation of spacer aromaticity, a spin crossover from thienylene/furylene-linked quinones DPP2q/DPP3q to phenylene-bridged biradical DPP1?? (y0 = 0.75) with a singlet open shell ground state (?EST = 19 meV) was achieved.The content of this RSS Feed (c) The Royal Society of Chemistry
