Acid‐Responsive N‐Heteroacene‐Based Material Showing Multi‐Emission Colors
An acid-responsive N-heteroacene-based material has been prepared, which shows a blue emission color in a film. The protonation of this material in a thin film gives rise to remarkable changes in luminescent color compared to that in solution states. As the protonation of N-heteroacene molecules in films gradually occurs, their emission color can be tuned by adjusting the exposure time of the t...
متن کاملA dual-stimuli responsive small molecule organic material with tunable multi-state response showing turn-on luminescence and photocoloration.
A multi-stimuli responsive small molecule organic material has been developed, which for the first time exhibits dual-wavelength response to render photocoloration under visible light and turn-on luminescence under UV light. The colored product can be bleached and shows turn-on luminescence again when re-exposed to UV light.
متن کاملAcid‐Responsive Absorption and Emission of 5‐N‐Arylaminothiazoles: Emission of White Light from a Single Fluorescent Dye and a Lewis Acid
Solutions of 5-N-arylaminothiazoles containing pyridyl groups exhibited clear halochromism and halofluorism upon addition of Brønsted and Lewis acids. The addition of triflic acid to solutions of 5-N-arylaminothiazoles in Et2O induced bathochromic shifts of the absorption and emission bands. DFT calculations suggested that the spectral changes arise from the protonation of the pyridyl group of ...
متن کاملCover Picture: Acid‐Responsive Absorption and Emission of 5‐N‐Arylaminothiazoles: Emission of White Light from a Single Fluorescent Dye and a Lewis Acid (ChemistryOpen 5/2016)
The Front Cover picture shows structures of the key compounds and the change in the fluorescence. Although electron-donating and -accepting groups of monocyclic 5-N,N-diarylaminothiazoles are not in the same plane but highly deviated, they show relatively strong fluorescence from blue to orange. In particular, the addition of Brønsted and Lewis acids to 5-N,N-diaryl-2-(4-pyridyl)thiazoles shift...
متن کاملMultistimuli-Responsive Luminescence of Naphthalazine Based on Aggregation-Induced Emission
Stimuli-responsive luminescent materials, which are dependent on changes in physical molecular packing modes, have attracted more and more interest over the past ten years. In this study, 2,2-dihydroxy-1,1-naphthalazine was synthesized and shown to exhibit different fluorescence emission in solution and solid states with characteristic aggregation-induced emission (AIE) properties. A remarkable...
