a, Snapshots of the phase transition visualized at 730 nm. b, Histogram analysis of the 1L (left) and 2L (right) regions. c, Selected reaction dynamics from two different points of the 2L indicated in a. Both spots are located at a similar distance (1 μm) from the edge. d, Snapshots of the phase transition visualized at 455 nm. e, Histogram analysis of the 1L (left) and 2L (right) regions. f, Power dependence of the reaction dynamics under 455 nm laser illumination for three different flakes. Each curve was obtained 1 μm away from the 2L/glass edge of the studied sample. Histograms are normalized to the mean of the intensity distribution 1 min after n-BuLi was added. Scale bar, 5 μm (a,d).
