51_29c/2012Inside Back Cover: Copper Catalyst Activation Driven by Photoinduced Electron Transfer: A Prototype Photolatent Click Catalyst (Angew. Chem. Int. Ed. 29/2012)

As light changes night (yin) into day (yang), irradiation of the click-inactive copper(II) tren ketoprofenate complex triggers an efficient photoinduced electron-transfer process to provide a highly active copper(I) tren click catalyst. In their Communication on page 7137 ff., J.-M. Vincent et al. also show that by simply introducing air into the reaction medium the catalysis can be switched off, and then on again by bubbling argon followed by irradiation.
