Comparison of the photoinduced surface topologies. a Surf1c, b Surf1c+2c, and c Surf2c: pale blue substrate and dark blue crystals correspond to crystals of open- and closed-ring isomers, respectively. SEM images of each surface; d and g: surface with needle-shaped crystals of 1c, e and h: surface with needle-shaped crystals of 1c and 2c, f and i: surface with needle-shaped crystals of 2c. Scale bars: 5 μm for d–f and h images, which are magnified 2000 times; 10 μm for g and i images, which are magnified 1000 times
