Changes of Photochromic Single Crystals

Dynamics of Surface Morphology Changes of Photochromic Single Crystals... [Pg.216]

Irie, M., Kobatake S., and Horichi M. Reversible surface morphology changes of a photochromic diarylethene single crystal by photoirradiation- Science 2001, 291, 1769-1772. [Pg.262]

The C-C distance dependence on photoswitching has been demonstrated using the bis(benzothiophene) series 1-10, all of which are photochromic in solution [27, 28], Derivatives 2-4 and 7-10 (Chart 21.1) all show single-crystal photochromism however, 1,5 and 6 have C-C distances that are too large to allow cyclization (4.35, 4.29 and 4.28 A, respectively) and crystals of them do not change color when irradiated with UV light. [Pg.786]

As the geomeMcal structural changes are relatively small in the photochromic reactions, most of these reversible photoreactions could also proceed in the crystalline state. Thus, diarylethenes also exhibit crystalline state photochro-2.3 Benzopyran and naphthopyran (chromene) mism. Single crystals of the cocrystals with two or... [Pg.1989]
