AbstractA new tetraphenylethene functionalized beta-diketonate boron luminogen BF2-TPE has been designed and successfully synthesized, and its aggregation induced emission (AM) characteristics and the mechanofluorochromic (MFC) behaviors have been investigated in detail. The results showed that boron complex BF2-TPE could emit intense yellow fluorescence in the solid state (lambda(em) = 544 nm, Phi(f) = 92.5%) and exhibited obvious AIE characteristics (alpha(AIE) = 231). More interestingly, the compound showed the reversible MFC behavior between the crystalline and the amorphous states. Simple mechanical force could change the emission color of BF2-TPE solid from initial yellow (544 nm) to final orange-red (606 nm), affording high contrast mechanofluorochromism with large spectral shift of up to 62 nm. The results obtained would be of great help in designing new MFC materials. (C) 2016 Elsevier Ltd. All rights reserved.
