Albuquerque, R. Q. Kühni, Joël Belser, Peter Cola, Luisa De 2010-01-04 The reversible photoisomerization of a derivative of spiropyran at the level of a single crystal by using zeolite L is demonstrated. The synthesized spiropyran exhibits rare negative photochromism when dissolved in a 1:1 mixture of H₂O and EtOH The spiropyran is functionalized predominantly at the channel entrances in the case of 4 μm long crystals application/pdf https://folia.unifr.ch/global/documents/301350 https://folia.unifr.ch/documents/301350/files/kuehni_rps.pdf https://folia.unifr.ch/documents/301350/files/kuehni_rps_sm.pdf eng info:eu-repo/semantics/altIdentifier/doi/10.1002/cphc.200900860 info:eu-repo/semantics/openAccess License undefined ChemPhysChem. - 2010, vol. 11, no. 3, p. 575-578 Photochemistry Photoisomerization Single crystals Spiropyran Zeolites info:eu-repo/classification/udc/54 On the reversible photoisomerization of spiropyran-modified zeolite L single crystals http://purl.org/coar/resource_type/c_6501
