| Abstract |
We report red fluorescent nanofibers generated via the self-assembly of new AIEE-active azobenzene chromophores. The combination of our spectroscopic results, DFT calculations, and the Rietveld refinement of the XRD data for the crystalline structures reveals that the partially increased planarization and inclined arrangements of the chromophores are responsible for the red shift in the absorption bands and for the increase in the fluorescence efficiency. The enhanced red fluorescence of the fibrous structures can be switched off by pressing, rubbing, or annealing. Our findings may be applicable to the development of stimuli-responsive luminescent materials that
range from optoelectronic devices and sensors to fluorescent polarizers combined with unidirectional molecular arrangements in polymeric objects. |
