Abstract

Abstract: A multiple luminescence colors system was facile constructed based on the supramolecular assembly of anionic β-cyclodextrin, dodecayltrimethylaminium bromide (DTAB ), a naphthalimide dye (G 1 ) and a benzothiadiazole derivative (G 2 ). Significantly, the fabricated system exhibited highly efficient energy transfer from G 1 to G 2, accompanying by fluorescence color change from blue to yellow, including white light. Furthermore, the white light emission supramolecular assembly was constructed from anionic cyclodextrin with low degree of substitution and DTAB exhibited reversible temperature responsiveness with fluorescent color changes from white to yellow.
