摘要：

This report describes the multiple luminescent switching of pyrenyl-based acylhydrazone derivative PAH-8. Firstly, PAH-8 shows an uncommon aggregation-induced emission (AIE) phenomenon. Secondly, PAH-8 xerogel from DMSO shows mechanofluorochromic behavior, its maximum emission at 458 nm shifts to 514 nm upon grinding. Thirdly, PAH-8 precipitate from THF exhibits mechanofluorochromic behavior, whereas no mechanofluorochromic behavior was observed for the drop-casting film of PAH-8 solution in THF. In addition, the PAH-8 xerogel exhibits the photo-fluorochromic behavior. The different luminescent property of PAH-8 is attributed to the switch of self-assembled structures.
