Reversible Optical Writing and Data Storage in an Anthracene‐Loaded Metal‐Organic Framework
摘要： Metal-organic frameworks (MOFs) enable the design of host-guest systems with specific properties. In this work, we show how confinement of anthracene in a well-chosen MOF host leads to reversible yellow-to-purple photoswitching of fluorescence emission. This behavior has not been observed before for anthracene, either in pure form or adsorbed in other porous hosts. The photoresponse of the host-guest system is caused by the photodimerization of anthracene, which is greatly facilitated by the pore geometry, connectivity and volume as well as the structural flexibility of the MOF host. The photoswitching behavior is used to fabricate photopatternable and erasable surfaces that, in combination with data encryption and decryption, hold promise in product authentication and secure communication applications.
