Patel, D. G.; Benedict, J. B.; Kopleman, R. A.; and Frank*, N. L. Photochromism of a Spirooxazine in the Single Crystalline Phase Chem. Comm. 2005 17, 2208-2210. DOI: 10.1039/b417026a
The single crystals of a closed form spirooxazine spiro[azaho-moadamantane-isoquinolinoxazine] were found for the first time to undergo photocoloration processes consistent with photochromism in the single crystalline phase.
