• Resumen

  • On Tuesday, March 14, 2000, at Cornell College, Mount Vernon, Iowa, two students who prepared the photochromic compound 2-(2,4-dinitrobenzyl)pyridine obtained their product as a single crystal, one weighing 864 mg and the other 891 mg. As far as we know, this has happened only once before, also at Cornell College in Iowa. The web version of this paper includes a time-lapse video of the photochromic conversion in which the original brown-sugar brown crystals turn into the blue-jeans blue form under the influence of the photographer's floodlight.
