Molecular self-assembly provides the desired functions to substrates, but investigation and control of its dynamics is challenging for the large area over which it must be detected. Here the authors report the use of graphene field effect devices to monitor with sub-second time resolution the photoinduced supramolecular assembly of a spiropyran derivative on graphene, covering an area of 100 × 100 μm2.
