Cao, Xinhua published the artcileFluorescence and Morphology Modulation in a Photochromic Diarylethene Self-Assembly System, COA of Formula: C15H14Cl2S2, the publication is Langmuir (2011), 27(8), 5090-5097, database is CAplus and MEDLINE.
Switchable supramol. self-assemblies on the basis of interaction between melamine group containing photochromic diarylethene unit (DTE) and naphthalimide derivate (1) were designed and fabricated. 1 can gelate several aprotic solvents with different morphologies. The gel turned into partial gel in Et acetate with the addition of DTE as a guest mol. Both the absorption and fluorescence spectra of the assembly can be reversibly switched by alternating UV/visible light irradiation Meanwhile, the morphol. of the coassembly of 12·DTE changed to film from original pieces of gel 1 in Et acetate. When 12·DTE was irradiated by UV light, the film morphol. was converted into aggregated flakes. Moreover, the surface wettability of the complex can also be switched by light irradiation The photochromic diarylethene unit is able to modulate the fluorescence and morphol. of the assembled system only by virtue of light irradiation Therefore, these results provide further insights into fluorescence and morphol. controlling, especially application in upscale smart responsive materials.
