Abstract

original image

In goldenem Weißlicht erscheint die Zuschrift von D. Li und Mitarbeitern auf S. 13714 ff. Sie knüpfen den organischen Chromophor Thiophen an einen klassischen dreikernigen Gold(I)-Pyrazolat-Cluster, der eine aurophile Phosphoreszenz ausstrahlt. Die kooperative duale Emission im blaugrünen und orangeroten Bereich sorgt für das weiße Leuchten dieser Verbindung im Festkörper, unterstützt durch ein im roten Bereich emittierendes kristallines Polymorph – eine ungewöhnliche Beobachtung in der Photochemie von Gold.
