英文摘要	Switchable supramolecular self-assemblies based on the interaction between pyridine group containing diarylethene unit (BTEPy) and carboxylic acids were designed and fabricated in this report. Fluorescent enhancement was observed in all of these assembled systems not only in solution, but also in the solid state as well as in the nanoparticles. A clear red-shift emerged in the solid film of the assembled system with BTEPy as a single fluorophore. Fluorescent photochromic organic nanoparticles were also realized in this system. When BTEPy interacted with a proton donor containing a BODIPY dye, the "concentration quenching'' problem in the solid state was alleviated due to the hydrogen bond formation and an energy transfer process, with a 65 nm blue shift of the fluorescence. The solid state fluorescence of all these assemblies was effectively switched by alternating irradiation with UV and visible light. Moreover, with the separate wavelengths of writing, reading and erasing cycles in the BODIPY system, control of the fluorescence intensity in a reversible manner without causing destruction in readout capability was realized. The formation of hydrogen bonds between the pyridine group and carboxylic acids of these components was verified by FT-IR, XPS and H-1 NMR.; http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000247188000002&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701 ; Chemistry, Physical; Materials Science, Multidisciplinary; SCI(E); EI; 48; ARTICLE; 24; 2483-2489; 17
