A triphenylamine-based acylhydrazone derivative (TBHM) was synthesized, and its emission properties either in solution or in the solid state were studied. It was demonstrated that TBHM showed a significant solvation effect, and the TBHM solution exhibited a very strong fluorescence quenching effect in the presence of iron ions with the detection limit of 9.7 × 10⁻⁷ M. In addition, TBHM displayed reversible blue and cyan emissions upon being ground and annealed. Furthermore, TBHM exhibited significant reversible acid/base induced fluorescence conversion characteristics in both organogel and xerogel states due to the protonation effect.

三苯胺取代的酰基hydr衍生物的多重刺激响应行为

合成了基于三苯胺的酰基hydr衍生物（TBHM），研究了其在溶液或固态下的发射性能。已经证实，TBHM呈显著溶剂化作用，且TBHM溶液表现出在铁离子的存在下，用9.7×10的检测极限的非常强的荧光淬灭效应^-7 M.另外，TBHM显示可逆蓝色和青色的排放在被研磨和退火后。此外，由于质子化作用，TBHM在有机凝胶和干凝胶状态下均表现出显着的可逆酸/碱诱导的荧光转换特性。
