Angewandte Chemie International Edition, EarlyView.Reducing a nitro‐derivatized arylimido‐polyoxometalate (POM) reversibly switches on its second‐order NLO response, contrasting with prior donor‐functionalized systems that switch off upon reduction. Attenuation of charge‐transfer (CT) to the POM upon reduction gives a more strongly dipolar imido/π‐bridge to ─NO2 CT, signal enhancement of up to 15× (β ...
