Confounding color changing crystal!

Caption

Photochemical reactions were thought to occur uniformly so that when light shines on crystals evenly, they change color evenly. But a research group at Osaka Metropolitan University has discovered that a photomechanical molecular crystal, 2,5-distyrylpyrazine (DSP), undergoes photochemical reactions differently, with the color change spreading from the crystal’s edges and propagating to its center.
