设计合成了一种基于水杨醛的酰腙衍生物(Z)-N'-[4-(二乙基胺基)-2-羟基苯亚甲基]苯甲酰肼(DHBH). 该化合物不仅表现出优良的聚集诱导发光(AIE)性能, 而且表现出可逆的力致荧光变色性能. 粉末X射线衍射和场发射扫描电镜结果表明, 该DHBH在外界压力刺激下发生力致荧光变色性能的原因是其晶态与无定形态之间的相互转化. 此外, DHBH可以选择性地识别铝离子, 并且显示出很好的抗干扰性, 对铝离子的荧光分析检测限为4.01×10–9 mol/L.

In this work, a versatile salicylaldehyde-based acylhydrazone compound (Z)-N'-(4-(diethylamino)-2-hydroxy- benzylidene)benzohydrazide (DHBH) has been designed and easily synthesized. And it not only showed aggregation-induced emission (AIE), but also reversible mechanochromic luminescence. The results of powder X-ray diffraction (PXRD) and field emission scanning electron microscopy (FESEM) revealed that the mechano?uorochromic (MFC) mechanism was the transformation between ordered crystalline and amorphous states upon external stimuli. In addition, compound DHBH displayed selective turn-on fluorescence with Al3+ and the probe exhibited good response and anti-interference performance. The detection limit for Al3+ was calculated to be about 4.01×10–9 mol/L.

Key words: mechano?uorochromic luminescence, aggregation-induced emission, aluminium ion, acylhydrazone
