Photodoping-based broadband photochromism of semiconductor nanocrystals under air operated by a supramolecular gel

We herein report photodoping and thereby photochromism of semiconductor nanocrystals under air in a temperature-responsive supramolecular gel and its back reactions induced by direct heating or near-infrared photothermal conversion. We also present their application to the spatiotemporal patterning of photoluminescence.
